http://www.rgraph.net RGraph: Free HTML5 and JavaScript charts - news and updates http://www.rgraph.net/download Sun 19 May 2013 16:00:00 +0000 A new beta release is now available. This release contains documentation updates, bug fixes and the rewrite of the key has commenced. Even so - the key should still be working and it should also be a little faster - though you are unlikely to notice this. http://dev.rgraph.net/blog/2013/may/an-example-of-a-rectangular-pie-chart.html Fri 17 May 2013 14:00:00 +0000 A new demo is available that shows you how you can achieve a rectangular Pie chart effect by setting a large radius for the Pie chart. Since the Pie takes up the entire canvas a key is used instead of labels. http://www.rgraph.net/blog/2013/may/an-example-bar-in-bar-chart.html Fri 17 May 2013 11:00:00 +0000 A new demo is available that shows you how you can combine two Bar charts to create a "bar-in-bar" effect. This example shows how it could be used to represent supplies vs sales of cars. http://www.rgraph.net/download Sun 5 May 2013 16:00:00 +0000 A new beta is now available. This release changes the way that methods are added to objects. Previously functions have been assigned to each objects prototype - but now functions are added in each objects constructor when you create the object. This means that, because of JavaScripts lexical scoping, references to commonly used variables can be kept in the constructor but will still be available to methods. The chart libraries have undergone a large "standardisation" as a result so there are now common references used throughout the libraries: ca, co, prop and RG being short names for the canvas, the context, the properties and the RGraph common object. http://www.rgraph.net/blog/2013/may/using-the-html5-canvas-globalcompositeoperation-setting-for-layered-drawing.html 4 May 2013 22:00:00 +0000 This is a demonstration of how the globalCompositeOperation setting can be used in order to draw "behind" any content that's already on the canvas. http://www.rgraph.net/blog/2013/may/using-the-html5-canvas-globalcompositeoperation-setting-for-layered-drawing.html 4 May 2013 22:00:00 +0000 This is a demonstration of how the globalCompositeOperation setting can be used in order to draw "behind" any content that's already on the canvas. http://www.rgraph.net/blog/2013/april/an-example-of-the-html5-canvas-todataurl-function.html Fri 26 Apr 2013 20:00:00 +0000 A new example of the HTML5 canvas toDataURL() function is available. This function allows you to get a base64 encoded PNG representation of the canvas. You can use this function to save a bitmap copy of the canvas. http://www.rgraph.net/blog/2013/april/an-example-of-html5-canvas-images.html Wed 24 Apr 2013 20:00:00 +0000 A new example of HTML5 canvas images is available. It shows you how to use the function, one of the major pitfalls and a few examples of it being used. http://www.rgraph.net/blog Sat 20 Apr 2013 18:00:00 +0000 The RGraph.AJAX function now has a few new additional functions that will help with data types. Because AJAX responses are always strings (text) they need to be converted to the relevant data type (eg numbers) before they can be given to RGraph. The new functions are: RGraph.AJAX.getNumber(url, callback), RGraph.AJAX.getString(url, callback) RGraph.AJAX.getCSV(url, callback[, seperator]), RGraph.AJAX.getJSON(url, callback) http://www.rgraph.net/blog/2013/january/an-example-of-html5-canvas-drag-n-drop.html Wed 17 Apr 2013 21:00:00 +0000 The example of drag 'n' drop has been updated to use "click to pick up, click to put down". This makes the whole process less error prone and avoids any selection peculiarities. http://www.rgraph.net/blog/2013/april/an-example-of-html5-canvas-gradients.html Wed 17 Apr 2013 18:00:00 +0000 A new article is available which details HTML5 canvas gradients - both linear and radial. http://www.rgraph.net/blog/2013/april/an-example-of-getting-html5-canvas-mouse-coordinates.html Tue 16 Apr 2013 19:00:00 +0000 A new article is available which shows you how you can use the RGraph.getMouseXY function to get the mouse coordinates. Whilst doing this can be as simple as using the .offsetX/Y properties - that way isn't portable or cross-browser compatible and nor does it take into account things like CSS borders or padding. The RGraph.getMouseXY function does all this for you. http://www.rgraph.net/blog/2013/april/an-example-of-the-html5-canvas-text-function.html Sun 14 Apr 2013 19:00:00 +0000 A new article is available which details the text functionality that is available with HTML5 canvas. It also shows an example of using the RGraph.Text2() function which provides extra functionality such as horizontal and vertical alignment, bounding boxes and carriage returns. http://www.rgraph.net/download Sat 13 Apr 2013 18:00:00 +0000 A new beta is now available. This release adds marginal speed increase to the Bar, Line, Fuel and Pie charts and adds thresholds for range charts: http://www.rgraph.net/demos/line-dual-color-range.html http://www.rgraph.net/demos/line-dynamic-updates-range.html, and you can now give datasets to the Radar chart as one big array. http://www.rgraph.net/blog/2013/april/html5-canvas-animation.html Fri 12 Apr 2013 18:00:00 +0000 A guide showing how you can perform animation with HTML5 canvas. This page shows a ball randomly bouncing around the canvas. http://www.rgraph.net/blog/2013/april/an-example-of-html5-canvas-shadows.html Fri 12 Apr 2013 12:00:00 +0000 A guide explaining the different methods that you can clear your canvas. For example clearRect, setting the canvas dimensions, composite operations - they all have their own advantages and disadvantages and this article explains them to you. http://www.rgraph.net/blog/2013/april/an-example-of-html5-canvas-shadows.html Thu 11 Apr 2013 23:00:00 +0000 This article is about shadows in HTML5 canvas. Shadows are simple things and can give your shapes a 3D appearance. http://www.rgraph.net/blog/2013/april/an-example-of-the-html5-canvas-clearrect-function.html Thu 11 Apr 2013 18:00:00 +0000 This article is about the clearRect function. The function can clear your canvas so that it's transparent again - not white. http://www.rgraph.net/blog/2013/april/an-example-of-the-html5-canvas-path-functions.html Thu 11 Apr 2013 12:00:00 +0000 A new blog article is now available that details HTML5 canvas paths and the functions that available to use in building them. It describes all of the path functions that are available to you and has an example of them in use. It also shows you how you can use the isPointInPath function for click detection. http://www.rgraph.net/blog/2013/april/an-example-of-using-the-html5-canvas-clip-function-to-create-a-sliding-reveal-effect.html Sun 7 Apr 2013 19:00:00 +0000 A new blog article is now available that shows how you can use the HTML5 canvas clip function to create a sliding reveal effect. The effect is a simple horizontal reveal but more involved paths could be used instead of the rect() function if required (eg you could use the arc() function to create a circular reveal). http://www.rgraph.net/download Sat 6 Apr 2013 18:00:00 +0000 A new beta release of RGraph is now available. This release includes miscellaneous updates including: Added chart.labels.specific to the drawing API Y axis object; converted the Bar, Line, Pie and Fuel charts to the new convention for local canvas, context and property references (ca, co and prop); added dual color range charts - http://dev.rgraph.net/demos/line-dynamic-updates-range.html ; the horizontal bars code has been rewritten. http://dev.rgraph.net/demos/line-dynamic-updates-range.html Sat 6 Apr 2013 16:00:00 +0000 A new demo of the filled range chart using different colors for above and below a particular threshold (which is set at 25). http://dev.rgraph.net/demos/line-dual-color-range.html Fri 5 Apr 2013 15:00:00 +0000 A new demo is available of a two color filled range chart. It could used to show thresholds for example - temperature. http://www.rgraph.net/docs/release-notes-march-2013.html Sun 31 Mar 2013 17:00:00 +0000 A new stable release of RGraph is now available. This release contains two significant updates - a new scale generation function and a new text function which has also allowed for a new text drawing API object. You can download the new version at the RGraph website: http://www.rgraph.net/download http://dev.rgraph.net/docs/drawing-api-text.html Tue 19 Mar 2013 18:00:00 +0000 The drawing API has a new Text object which makes adding text to your charts a breeze. The text can also have tooltips and/or events asociated with it. http://dev.rgraph.net/docs/howto-rgraph-text2.html Tue 19 Mar 2013 18:00:00 +0000 Along with the new text drawing function here is a HOWTO guide that illustrates how you can make use of this new function. http://www.rgraph.net/download Sun 17 Mar 2013 17:00:00 +0000 A new beta release of RGraph is now available. This release includes documentation updates, a few new HOWTO documents and most notably a new Text drawing API object. This new object allows you to easily add text to your chart which supports the click and mousemove events and is configured in the standard way using the Get/Set methods.This beta is using the new scale generation function that RGraph now has - RGraph.getScale2(). This function allows any number of Y labels so if, for example, you have a maximum value of 700 you can now have 7 labels. http://www.rgraph.net/download Sat 2 Mar 2013 17:00:00 +0000 A new beta release of RGraph is now available. This release includes a new text function (called RGraph.Text2()). This new function is approximately twice as fast as the previous text function (though the actual speed increase is too small to be perceptible) - but more significantly it records the coordinates of the text. This means that you can use those coordinates along with the Drawing API Rect object to either make your text clickable or give it tooltips! Other Drawing API objects have also been added - the X axis and Y axis objects. These objects allow you to have extra axes - and can also have events or tooltips associated with them. You can download the latest RGraph beta at the link provided. http://www.rgraph.net/download Sun 24 Feb 2013 11:00:00 +0000 A new beta release is now available. This new release updates the front page of the website to show a 3D Pie chart (a HOWTO document is available that shows you to accomplish this). It also introduces the RGraph.Text2() function - which is a full rewrite of the RGraph.Text() function. With this new function the coordinates of the text are kept so you can now make the text clickable by adding a drawing API Rect object on top of it. Information on how to do this will follow. http://dev.rgraph.net/docs/howto-create-3d-pie-charts.html Fri 22 Feb 2013 14:00:00 +0000 A new HOWTO document is now available showing you how you can use the scale() function of the canvas to horizontally scale a Pie chart in order to achieve a 3D effect. http://dev.rgraph.net/tests/2013-02-28/text2.html Mon 18 Feb 2013 14:00:00 +0000 You can now have any number of labels you want on the Bar charts - not just 1/3/5/10. You will need to update the background grid and the number of Y ticks if you change it to an odd number. http://dev.rgraph.net/tests/2013-02-28/text2.html Thu 15 Feb 2013 15:00:00 +0000 RGraph has a new text handling function: http://dev.rgraph.net/tests/2013-02-28/text2.html It removes support for angled text but instead it improves boxed text and more importantly - it records the coordinates of the text. This means that you can then use those coordinates to place a Rect drawing API object over them thus creatingg clickable text! http://www.rgraph.net/blog/2013/february/an-example-of-the-html5-canvas-rotate-function.html Sun 10 Feb 2013 18:00:00 +0000 This is a demo of the rotate canvas function - which rotates the canvas as well as the RGraph.RotateCanvas() API function which in some cases can be easier to use. http://dev.rgraph.net/demos/bar19.html Sat 9 Feb 2013 12:00:00 +0000 A new demo is available that demonstrates the new drawing API objects - the X axis and Y axis objects. http://dev.rgraph.net/demos/bar19.html Also an existing demo has been updated http://dev.rgraph.net/demos/line08.html http://dev.rgraph.net/blog/2013/february/an-example-of-the-html5-canvas-transform-function.html Wed 6 Feb 2013 18:00:00 +0000 This is a look at the setTransform() and transform() functions of HTML5 canvas. Transformations can allow you to perform actions on the canvas - sometimes significantly altering how it appears. http://www.rgraph.net/forum/2013/02/04/rgraph-set-method-chaining-202651.html Mon 4 Feb 2013 21:00:00 +0000 As of the next RGraph release (beta and stable) you will be able to chain Set() method calls. For an example see the post in the forum. It won't mean any speed increase - but it may suit your coding style better. http://www.rgraph.net/blog/2013/february/an-example-of-the-html5-canvas-ispointinpath-function.html Sat 2 Feb 2013 18:00:00 +0000 A new article is available that demonstrates the isPointInPath function - which is a function that can be used for hit testing to see if the mouse cursor or a click is over a particular shape. As a result your hit testing code can be reduced and greatly simplified. http://www.rgraph.net/docs/release-notes-january-2013.html Thu 31 Jan 2013 21:00:00 +0000 The January stable version of RGraph has been released. This release contains a significant speed up for effects (everything is affected but you'll only notice the increase in effects). You can read the full release notes at the link provided. http://www.rgraph.net/blog/2013/january/an-example-of-the-html5-canvas-quadraticcurveto-function.html Tue 29 Jan 2013 21:00:00 +0000 As it's less of an RGraph HOWTO guide and more a general information post the quadraticCurveTo() function guide has been converted from a HOWTO guide to a blog post. It's been embellished a little and colors have been added to help you identify the points. http://www.rgraph.net/blog/2013/january/an-example-of-the-html5-canvas-beziercurveto-function.html Tue 29 Jan 2013 15:00:00 +0000 As it's less of an RGraph HOWTO guide and more a general information post the bezierCurveTo() function guide has been converted from a HOWTO guide to a blog post. It's been embellished a little and colors have been added to help you identify the points. http://www.rgraph.net/blog/2013/january/an-example-of-the-html5-canvas-clip-function.html Tue 29 Jan 2013 12:00:00 +0000 As it's less of an RGraph HOWTO guide and more a general information post the clip() HOWTO guide has been moved to a blog post. http://www.rgraph.net/blog/2013/january/the-difference-between-rect-strokerect-and-fillrect.html Mon 28 Jan 2013 23:00:00 +0000 A new article is available that explains the difference between the strokeRect, fillRect and rect() functions. http://www.rgraph.net/blog/2013/january/html5-canvas-path-objects.html Mon 28 Jan 2013 00:00:00 +0000 A new article is available that explains the new HTML5 canvas path objects - a forthcoming addition to the canvas specification that make dealing with multiple paths easier and also make hit testing easier. http://www.rgraph.net/docs/drawing-api-xaxis.html Sat 26 Jan 2013 18:00:00 +0000 Here is a preview of the forthcoming (February) X axis drawing object: http://www.rgraph.net/docs/drawing-api-xaxis.html You can currently get extra X axes with the RGraph.DrawXAxis() API function but to use them in conjunction with interactive features (eg tooltips) you have to add them using the ondraw event - otherwise they won't get redrawn automatically. Drawing API objects on the other hand DO get redrawn automatically so when they've been converted they'll be easier to significantly use. http://www.rgraph.net/blog/2013/january/html5-canvas-hit-regions.html Thu 24 Jan 2013 21:00:00 +0000 A new article is available that explains the new HTML5 canvas hit regions - a forthcoming addition to the canvas specification that make adding "hotspots" to your canvas easy and handling subsequent events. http://www.rgraph.net/blog/2013/january/html5-canvas-ellipse.html Wed 23 Jan 2013 19:00:00 +0000 A new article is available that shows the ellipse() function that is a new method added to the canvas specification. Currenty no browsers have support for this function, but the page does demonstrate a method for drawing ellipses using the bezierCurveTo() function. http://www.rgraph.net/blog/2013/january/an-example-of-html5-canvas-drag-n-drop.html Thu 17 Jan 2013 23:00:00 +0000 This is an example of how you can achieve drag 'n' drop between canvas tags. It shows drag 'n' drop for an image - and when moving from canvas to canvas it just updates the relevant canvas that the canvas should be drawn on. http://www.rgraph.net/download Thu 17 Jan 2013 23:00:00 +0000 A new beta release is now available to download. This release improves the speed of the RGraph.Text() function significantly meaning that effects in Firefox, Opera and Safari are smoother - particularly the Bar chart Wave effect. Download it at the RGraph website: www.rgraph.net/download http://www.rgraph.net/blog/2013/january/measuring-text-height-with-html5-canvas.html Mon 14 Jan 2013 23:00:00 +0000 A new demonstration of a function that can measure text dimensions (width AND height). It works by adding a DIV to the document and then measuring it. The function comes from the RGraph core common file but has been altered so that it can be used as a stand-alone function. http://www.rgraph.net/download Sun 13 Jan 2013 14:00:00 +0000 A new beta release is now available. This release contains documentation updates and also adds two new properties to the Meter chart - chart.angles.start and chart.angles.end (which if specified should be given in radians). http://www.rgraph.net/download Wed 9 Jan 2013 17:00:00 +0000 A new beta release is now available. This release adds new options to the RGraph.Draw(X|Y)Axis methods and the Radar, Rose and Rscatter background grids have been altered slightly. Examples of these can be found here: http://dev.rgraph.net/tests/2013-01-13/ http://www.rgraph.net/blog/2013/january/html5-canvas-dashed-lines.html Sat 5 Jan 2013 17:00:00 +0000 A new article is available that shows the new setLineDash() function that has been added to canvas. Only Chrome currently supports this so to to see it you'll need to use that browser. This function allows you specify how you would like your lines to appear with regard to dash, dotted or solid. http://dev.rgraph.net/docs/api.html Thu 3 Jan 2013 18:00:00 +0000 New options have been added to the RGraph.DrawXAxis() and RGraph.DrawYAxis() functions. They allow you to control the end-of-axis tickmarks (useful when combining the axes), invert the scale (so 0 is at the top/left) and hide the relevant axis (whilst still showing labels, titles etc). http://dev.rgraph.net/demos/line14.html Tue 1 Jan 2013 14:00:00 +0000 Added a new demo of a basic black and white chart (which does actually require a few defaults changing): http://dev.rgraph.net/demos/line14.html http://www.rgraph.net/download Mon 31 Dec 2012 17:00:00 +0000 A new stable version is now available. You can read the release notes here: http://www.rgraph.net/docs/release-notes-december-2012.html The major addition this month is the Radar chart Trace effect along with other smaller tweaks and new features. http://www.rgraph.net Sat 29 Dec 2012 17:00:00 +0000 A new beta version of RGraph is now available. This beta is mainly focused on website changes and updates. For instance the documentation changes already noted and you can now also subscribe to the forum for email updates so that you no longer have to use RSS - you also now get new messages delivered direct to your inbox. http://dev.rgraph.net/docs/ Sun 23 Dec 2012 12:00:00 +0000 ...but not that you'll notice. The RGraph API docs have been significantly overhauled but all the changes are "behind the scenes" so you shouldn't really notice anything. If anything a few minor errors and things that were out of date have been corrected. The next beta release will move the docs on to the live website so if you notice anything peculiar after that point then please get in touch. http://dev.rgraph.net/demos/hbar04.html Mon 17 Dec 2012 18:00:00 +0000 A new grouped HBar example which shows off using the DrawXAxis() API function. http://dev.rgraph.net/docs/basic-web-workers.html Wed 12 Dec 2012 18:00:00 +0000 A new basic example of Web Workers (multi-threading for web pages) is now available. http://dev.rgraph.net/tests/2012-12-30/hprogress-bevel.html Wed 12 Dec 2012 18:00:00 +0000 A new demo of the HProgress, VProgress and their new bevel option (chart.bevel) is now available at the link provided. The option supports regular progress bars as well as those showing multiple values. http://www.rgraph.net/download.html Wed 12 Dec 2012 12:00:00 +0000 A new beta version of RGraph is available. A few new axis controls (chart.axis.linewidth, chart.numxticks, chart.numyticks) have been added which may mean that you might need to alter your ode slightly. Download the beta at the link provided. http://www.rgraph.net/download.html Sat 8 Dec 2012 17:00:00 +0000 A new beta of RGraph is now available. This version adds a few new tweaks as well as a new HOWTO that shows you how you can make transition using Contract and Expand effects. Download at the RGraph website: http://www.rgraph.net http://www.rgraph.net Fri 7 Dec 2012 17:00:00 +0000 The Facebook RGraph page has been published once again and you can reach it here via the link. http://dev.rgraph.net/docs/howto-custom-static-y-axis.html Wed 5 Dec 2012 21:00:00 +0000 The static Y axis example from the Miscellaneous documentation has been converted to a full HOWTO document with sample code and now also uses the API function RGraph.DrawYAxis(). http://dev.rgraph.net/tests/2012-12-30/ Sat 1 Dec 2012 13:00:00 +0000 Here are a few new examples of the Trace effect. The original now supports CSS 3D transforms - so when you use these on your canvas the Trace effect will work correctly: http://dev.rgraph.net/tests/2012-12-30/line-chart-trace.html And the second is a new effect - Trace2. Which is similar to the original Trace effect but differs in its implementation in that it uses the clip() function: http://dev.rgraph.net/tests/2012-12-30/line-chart-trace2.html There's also a new Contract effect that complements the Expand effect: http://dev.rgraph.net/tests/2012-12-30/contract.html And finally a new HOWTO document that demonstrates how to combine the Expand and Contract effects to make a transition: http://dev.rgraph.net/docs/howto-make-a-contract-expand-transition.html (currently lacking a little documentation). http://www.rgraph.net/docs/release-notes-november-2012.html Fri 30 Nov 2012 12:00:00 +0000 The November stable release of RGraph is now available. You can read the release notes for it at the link provided. Notable additions are the ability to make whole Radar chart data series clickable, the non-commercial license has been formalised to the Creative Commons Attribution NonCommercial license and the addition of a third party CSS animations library. http://www.rgraph.net/feedback.html Wed 28 Nov 2012 16:00:00 +0000 If you've been trying to add a testimonial/feedback for RGraph the form was broken - but it's now fixed so go right ahead and add it! http://www.rgraph.net/blog/2012/november/new-line-chart-trace-effect-using-the-clip-canvas-method.html Tue 27 Nov 2012 13:00:00 +0000 This is a demonstration of a new Line chart Trace effect implementation. The code necessary to achieve this is far more concise and the effect will function when combined with canvas 3D effects - as shown in Chrome, Safari and Firefox. http://www.rgraph.net/docs/howto-index.html Mon 26 Nov 2012 21:00:00 +0000 A couple of new HOWTO documents are now available. The first is an update of an example that was in the miscellaneous documentation for obtaining a static Y axis. This is particularly useful if you have a wide chart but wish to show it in a limited space - for example a timeline of sorts. And the second shows you an example of the new RGraph.DrawXAxis() function. This is a new function that allows you to have multiple X axes in a similar way to having multiple Y axes with the RGraph.DrawYAxis() function (which has been renamed from RGraph.DrawAxes() ). http://www.rgraph.net/blog/2012/november/bevelled-hprogress-using-clip.html Sun 25 Nov 2012 12:00:00 +0000 This is a new demo of using the clip() method to add a bevel effect to a horizontal progress bar. All being well this will be added as an option to the Hprogress, VProgress, Thermometer etc in the December or January release. http://www.rgraph.net Sat 24 Nov 2012 14:00:00 +0000 As of the next release - all being well - you'll be able to omit the "chart." from property names when configuring your charts eg obj.Set('gutter.top', 25); http://www.rgraph.net Sat 24 Nov 2012 10:00:00 +0000 The RGraph release process has undergone a few changes - and this will mean more reliable, quicker and more releases! http://dev.rgraph.net/docs/howto-3d-effect.html Mon 19 Nov 2012 17:00:00 +0000 The 3D example now uses the Expand effect. So it uses that as well as having the 3D transform. Because of limited support for 3D transforms this will only work fully in Chrome, Safari and Firefox. http://www.rgraph.net/blog/2012/november/use-canvas-transformations-to-create-zoom.html Sun 18 Nov 2012 17:00:00 +0000 A new blog article showing you how you can add a magnifying glass effect to your canvas (the effect will work with any canvas - not just RGraph charts). The article uses the canvas transformation methods - scale(), translate() and clip(). http://www.rgraph.net/docs/howto-use-the-html5-canvas-clip-method.html Sat 17 Nov 2012 22:00:00 +0000 This is a new HOWTO document that describes how to use the canvas clip() method. The method is not as well known or used but can be extremely useful in restricting drawing to a particular area - when you draw outside of the clipping region it's not drawn on to the canvas. http://www.rgraph.net/blog/2012/november/css-animations.html Wed 14 Nov 2012 12:00:00 +0000 This is an example of CSS animations and effects in-conjunction with RGraph charts. Keep in mind that most of the effects will only work with newer browsers. The relevant CSS file is distributed with RGraph in the CSS directory. http://www.rgraph.net/license.html#license.free Thu 8 Nov 2012 12:00:00 +0000 As of today the non-commercial license of RGraph has been formalised to the Creative Commons Attribution-NonCommercial 3.0 license. In effect little has changed - you can still use RGraph for free in non-commercial projects - and if you buy an RGraph license you can also use it in commercial projects. The new license does make things more "official" though. http://www.rgraph.net/blog/2012/november/filled-line-chart-with-shadow.html Wed 7 Nov 2012 14:00:00 +0000 The filled Line chart can now have a shadow if desired. The shadow is only applied to the actual line - now the filled section. Here is test page showing it in action. http://www.rgraph.net/blog/2012/november/an-adjustable-filled-line-chart-in-spline-mode.html Sat 3 Nov 2012 23:00:00 +0000 Here is a new demonstration of an adjustable filled spline chart. It can be adjusted just like a regular line chart by clicking and dragging the points up and down. It's also animated using the UnfoldFromCenter effect. http://www.rgraph.net/docs/release-notes-october-2012.html Wed 31 Oct 2012 11:00:00 +0000 A new stable release of RGraph is now available. This release introduces dollar objects which make referencing specific elements (bars/points/segments etc) of your charts very easy - eg: bar.$2.onclick = function (e, shape) {} It also switches back to DOM2 events, but without any slowdown. So this frees up the DOM1 events for you to use if you so wish. You can read the full list of changes here in the release notes at the link provided. http://www.rgraph.net/blog/2012/october/new-html5-canvas-features.html Wed 31 Oct 2012 11:00:00 +0000 This is an preview of new HTML5 canvas features that have been added to the HTML5 specification. Things like path objects, hit regions and other enhancements that will server to make canvas much easier to use. http://dev.rgraph.net/tests/radar/radar3.html Mon 22 Oct 2012 21:00:00 +0000 This is a demo of a forthcoming Radar chart feature where the whole data series is a hotspot. Here it only responds to the mousemove event. It could be used to show information about the data series in question. http://dev.rgraph.net/tests/_misc/emulated-html5-canvas-path-object.html Thu 18 Oct 2012 18:00:00 +0000 This is an experimental object for recording paths with HTML5 canvas. Similar in concept to the forthcoming Path object it records the operations that you perform so that when needed it can replay them and then use the .isPointInPath() method to test coordinates. The whole thing could be optimised (eg reduce the code to a simple function, use an off-screen canvas for testing) but the concept should be clear from this. http://www.rgraph.net Tue 16 Oct 2012 13:00:00 +0000 A new release of RGraph is now available. This release fixes a few bugs and adds more support for the new easy method of specifying gradients: Gradient(white:red) This is still to be documented and support for it is not yet complete - but the front page Bar chart uses it if you want to see an example. http://dev.rgraph.net/tests/radar/radar3.html Mon 22 Oct 2012 21:00:00 +0000 This is a preliminary demo of a stacked Radar chart where the whole data series is a hotspot and triggers the mousemove event. Currently this is purely a demo but will be eventually made into a usable option. http://dev.rgraph.net/ Sat 6 Oct 2012 21:00:00 +0000 The tooltip placement for a few chart types has been adjusted. The adjustment means that tooltips for bar shapes are now positioned above (or below in a few cases) the bar. An example can be seen in the Bar chart on the front page of the dev site. http://www.rgraph.net/docs/pseudo-standard-events-dollar.html Fri 5 Oct 2012 20:00:00 +0000 A new beta release of RGraph is now available. This is the first release that supports the dollar objects - a very easy way of adding event listeners to specific bars/segments/points and should help to make RGraph much more usable. More information can be found here: http://www.rgraph.net/docs/pseudo-standard-events-dollar.html http://dev.rgraph.net/tests/2012-10-27/dollar-bar.html Fri 28 Sep 2012 21:00:00 +0000 This link is a demonstration of a potentially new syntax for adding custom events. It won't replace the current chart.events.* properties but rather will be an addition to what's currently available. It does make adding event listeners to specific shapes a lot easier - sample source is shown on the page. If it proves to be viable it will be rolled out across the chart types. http://www.rgraph.net/docs/release-notes-september-2012.html Fri 28 Sep 2012 12:00:00 +0000 A new stable release is now available. You can read the release notes on the release notes page (found in the documentation) and download it from the link above. Major improvements in this release include the addition of support for DOM1 style events which are much easier to add and also the Line chart now supports Catmull-Rom splines which are demonstrated on the front page. http://www.rgraph.net/forum Tue 25 Sep 2012 12:00:00 +0000 New and easier support for defining gradients is planned. Gradients currenty can be defined using the RGraph API functions but these can be unwieldly and verbose. So with the new format you will be to define gradients much like a regular color like this: Gradient(red, white) Very simple and very easy to use. The new format will be added to a small number of charts initially - expanding as time goes on. Any feedback can be posted in the support forum. http://dev.rgraph.net/tests/2012-11-30/clock.html Sat 22 Sep 2012 12:00:00 +0000 A new clock drawing API object to be added after the next stable release is this clock object. Resurrected from early adventures with HTML5 canvas, this new and improved clock can be added to your charts the same as any other drawing API object. http://www.rgraph.net/forum/2012/09/19/19th-september-2012-beta-release.html Wed 19 Sep 2012 12:00:00 +0000 A new RGraph beta release is now available. Get more details at the link. http://dev.rgraph.net/docs/adjusting_line.html Tue 18 Sep 2012 22:00:00 +0000 The adjustable Line chart example has been updated to be an adjustable Spline chart. http://www.rgraph.net/forum/dhsi/8th-september-2012-beta-release.html Sat 8 Sep 2012 22:00:00 +0000 A new RGraph beta release is now available. Get more details at the link. http://dev.rgraph.net/forum Thu 6 Sep 2012 22:00:00 +0000 A new RGraph public support forum is now available. It should currently be regarded as "beta" quality. It's also public so if you think the problem you're having is common then try searching the forum first. http://dev.rgraph.net/ Mon 3 Sep 2012 10:00:00 +0000 The chart.curvy option has been improved so that that line passes through all of the specified points. It's important to remember that curvy charts involve lines that do no always go directly from point to point - in order to make the line curvy. The front page chart has been updated to include this option - and you can see this on the dev site. http://www.rgraph.net/docs/howto-bezier-curves.html Sun 2 Sep 2012 18:00:00 +0000 This is a HOWTO document that illustrates how to use the .bezierCurveTo() function. It features an interactive example that helps to show you how the points that you supply to the function affect how the curve is drawn. It also shows you a resulting code example. http://dev.rgraph.net/docs/howto-quadratic-curves.html Thu 31 Aug 2012 18:00:00 +0000 This is a HOWTO document that illustrates how to use the .quadraticCurveTo() function. It features an interactive example that helps to show you how the points that you supply to the function affect how the curve is drawn. It also shows you a resulting code example. http://www.rgraph.net/docs/new-html5-canvas-features.html Thu 30 Aug 2012 21:00:00 +0000 This is a document descibing new HTML5 canvas features: Hit regions, Path objects, SVG path syntax and more. These new features mean added functionality and a much easier to use canvas API. They add a slight air of OO to HTML5 canvas and have the potential to increase the accessibility of the HTML5 canvas tag. They're only additions to the HTML5 specification at the moment and so may take some time before they're supported by browsers. Hopefully it will be IE11 at the most - by which time browsers with a shorter release cycle will have added support. Given the potential that the changes add - they're very exciting! http://www.rgraph.net Thu 30 Aug 2012 20:00:00 +0000 A new beta has beeen released. The major update for this release is the addition of the Drawing API which allows you to add various objects (only five at the moment) to your charts: circle, rectangle, images and two different styles of marker. Also added this release is the ability to specify custom events using a DOM1 style - much easier and more concise than previously. Also added recently was a page describing recent addiions to the HTML5 canvas spec which will make working with canvas much, much easier. These changes are described here: http://www.rgraph.net/docs/html5-canvas-new-features.html http://dev.rgraph.net/docs/howto-custom-labels.html Sun 26 Aug 2012 11:00:00 +0000 A new HOWTO document is now available showing you how you can use various RGraph features (ie the ondraw event, the .getYCoord() method and the .scale member variable) to draw a significantly customised scale on your chart. http://dev.rgraph.net/tests/2012-09-29/drawing.api.marker1.html Sat 25 Aug 2012 22:00:00 +0000 As part of the new drawing API this is an example of a new marker that can be added to your charts. It's clickable - supporting tooltips, highlighting and the chart.events.click and chart.events.mousemove properties. It can be used to highlight things on your chart providing extra information via the tooltip. There's also a different style of marker available called Marker2: http://dev.rgraph.net/tests/2012-09-29/drawing.api.marker2.html This can be used in a similar way but with a different style. http://dev.rgraph.net/tests/2012-09-29/drawing.api.label1.html Tue 21 Aug 2012 22:00:00 +0000 As part of a new API for components drawing there is now a new option for adding squares, circles and labels to your charts. The new components are treated much like charts and they act much like charts when it comes to interactive features, so you can use tooltips with them, or properties like chart.events.mousemove and chart.events.click. More components are planned (eg exclamations/alerts). http://www.rgraph.net Sat 19 Aug 2012 23:00:00 +0000 A new beta has beeen released. This release contains documentation and other miscellaeous updates. http://dev.rgraph.net/tests/2012-09-29/drawing.api.html Sat 18 Aug 2012 15:00:00 +0000 RGraph has a new drawing API, which can be used to draw shapes and labels on your charts. The shapes are all created using the RGraph system (eg the ObjectRegistry) so unlike if you draw on the canvas yourself you don't need to use the ondraw custom event. More shapes and labels are coming. http://dev.rgraph.net/docs/howto-datetime-chart.html Sat 4 Aug 2012 22:00:00 +0000 There's now a new HOWTO document showing the new Date/Time support: http://dev.rgraph.net/docs/howto-datetime-chart.html http://dev.rgraph.net/tests/scatter/date-range.html Sat 4 Aug 2012 19:00:00 +0000 The Scatter chart now has Date/Time support for X values. This means that you can give Date/Times as your X values. This should make using date/time based data much more intuitive. See the source of the link for how to do it and how simple it makes things. Underneath the Date.parse() function is used to convert the dates to numbers so any valid date accepted by that is acceptable. http://www.rgraph.net Sat 4 Aug 2012 15:00:00 +0000 A new beta version is now available. This version adds a few new properties to the Bipolar and Scatter charts and adds a new HOWTO document showing the ability to have multiple independent Y axes. http://www.rgraph.net Thu, 26 July 2012 15:00:00 +0000 A new stable version has been released. This versions adds new demos, Priority Support and the much easier to use DOM1 style custom events (eg ontooltip, ondraw etc). You can download the latest stable version at the RGraph website. http://www.rgraph.net Sat, 21 July 2012 17:00:00 +0000 A new beta is now available. This release adds documentation updates, support for DOM1 style custom events (which make adding custom events much easier) and Bubble chart support using the Scatter chart. http://dev.rgraph.net/demos/scatter03.html Thu, 19 July 2012 14:00:00 +0000 RGraph doesn't support bubble charts "out-of-the-box" but they can be achieved using the Scatter chart and the RGraph custom events. This shows an example Bubble chart. It also uses the the new style DOM1 ondraw event. http://dev.rgraph.net/demos/bar07.html Mon, 16 July 2012 18:00:00 +0000 RGraph now supports DOM1 style events for the custom event listeners. This makes for much easier installation of events, which can be seen at the linked bar07 demo page. http://www.rgraph.net Sun, 15 July 2012 11:00:00 +0000 A new beta is now available. This release adds documentation updates, a few new effects, the Fuel chart can now have a scale, a new HOWTO regarding the getXValue() method of the Scatter chart and the getValue() Scatter chart method has been renamed to getYValue(). http://dev.rgraph.net/demos/line08.html Sat, 14 July 2012 11:00:00 +0000 A new demo is now available of a Line chart combination that shows three axes instead of one or two. It's achieved by using three seperate Line chart objects and then drawing the third set of axes manually (for which a new function will be added to make life much easier). A new option to allow specifying the color of the Y axis title has also been added. http://dev.rgraph.net/demos/gauge04.html Fri, 13 July 2012 20:00:00 +0000 A new demo is now available of a Gauge chart that updates itself periodically using an AJAX call to get data from the server. There's also a new demo on the example page ( http://dev.rgraph.net/examples/gauge.html ) that shows how radically different the Gauge chart can appear. http://dev.rgraph.net/demos/gauge03.html Tue, 10 July 2012 13:00:00 +0000 A new demo is now available of a heavily customised Gauge chart. This demo utilises two new Gauge chart properties to set the start and end angles and also draws over the center bulb using the custom ondraw event. http://www.rgraph.net Fri, 08 July 2012 11:00:00 +0000 A new beta release is now available. This release adds a new CornerGauge Grow effect and updates the website with more testimonials. http://www.rgraph.net Fri, 06 July 2012 19:00:00 +0000 A new beta release is now available. This release adds a few new Bar chart options: chart.variant.sketch.verticals and chart.labels.above.specific. You can download the beta from the RGraph website. http://www.rgraph.net Wed, 04 July 2012 13:00:00 +0000 Follow RGraph on Facebook! RGraph now has a dedicated Facebook page: http://www.facebook.com/rgraph You can follow RGraph on Facebook for news and updates (news will also be posted on the RSS feed). http://dev.rgraph.net/demos/bar05.html Tue, 03 July 2012 18:00:00 +0000 A new test Bar chart showing a few new options to the sketch variant of the Bar chart. http://www.rgraph.net Mon, 02 July 2012 18:00:00 +0000 A new beta release is now available and this release includes the addition of the new CornerGauge chart. This is a new variant on a meter which may be suited to your control panel. http://dev.rgraph.net/tests/2012-06-30/corner-gauge.html Fri, 29 June 2012 23:00:00 +0000 A new type of chart is being added to RGraph - the CornerGauge. This is a Gauge that is vaguely similar to the regular Gauge chart but is only a "quarter" Gauge that may suit your page(s) better. http://www.rgraph.net Fri, 25 June 2012 23:00:00 +0000 A new beta is now available. This release optimises the Pie chart and also removes the Pie chart Wave effect. http://www.rgraph.net Fri, 22 June 2012 17:00:00 +0000 A new beta is now available. This release adds a new Scatter chart effect - Trace - which is similar to the Line chart Trace effect. Also introduced is Priority Support, which you can read about here: http://www.rgraph.net/support.html http://www.rgraph.net Thu, 14 June 2012 17:00:00 +0000 A new beta is now available. This update contains miscellaneous website updates - for more details take a look at the CHANGELOG file. http://dev.rgraph.net Mon, 4 June 2012 15:00:00 +0000 If you're using RGraph under the conditions of the non-commercial license you need to provide a backlink to the RGraph website - and now to make that easier there's a button next to the social icons that provides both the URL and the relevant HTML tag for you. http://dev.rgraph.net/docs/misc.html#clear.canvas Sat, 2 June 2012 15:00:00 +0000 Due to repeated support emails regarding using the same canvas with multiple charts there is now new doumentation about how you can prevent old charts from being redrawn on your canvas if you are using (for example) tooltips or other dynamic features. http://www.rgraph.net Fri, 01 June 2012 13:00:00 +0000 A new stable version is now available. This release has fewer changes than normal however one major change is that the documentation and examples have been unbundled from the download and are now exclusively available via the website. The website has also undergone a change in appearance which also bring benefits in both speed and maintainability. This change means that updates can be brought to the fore more quickly - eg new HOWTO documents and examples. You can download the latest RGraph at the website. http://www.rgraph.net Tue, 29 May 2012 12:00:00 +0000 A new beta is now available. The Gauge chart now has additional properties, the HBar chart supports chart.hmargin.grouped and the Rose chart has a few new properties related to the background "grid". http://dev.rgraph.net Sun, 27 May 2012 22:00:00 +0000 As part of the change to the examples and documentation being unbundled from the RGraph archive the website has undergone a small re-styling. Both navigation and appearance have been improved. You can see the changes at the development site: dev.rgraph.net As a result of this the next stable version will be released soon. http://www.rgraph.net Sat, 26 May 2012 17:00:00 +0000 There are new options for the Gauge and Radar charts. This beta release marks a change to the RGraph documentation and examples. From this point onwards they will no longer be bundled in the RGraph archive. You will still of oourse be able to view them at the rgraph.net website. http://www.rgraph.net Fri, 25 May 2012 17:00:00 +0000 The RGraph website and download archive are undergoing a raft of changes to make ongoing maintenance and updates easier to manage. The RGraph archive will no longer contain a copy of the website and documentation. For these you will need to visit the website (www.rgraph.net) itself. The archive will contain the library files of course but you will need to use the website to read the documentation and look at examples. http://dev.rgraph.net/tests/_misc/html5-audio.html Sat, 19 May 2012 16:00:00 +0000 An old HTML5 audio demo has been resurected and is now available. It uses a small MP3 file. http://dev.rgraph.net/tests/_misc/html5-video.html Sat, 19 May 2012 16:00:00 +0000 An old HTML5 video demo has been resurected and is now available. It also shows off CSS3 3D transformations by rotating the video around all 3 axes in a loop. The video is WebM video so you'll need to use Google Chrome to view the page. http://dev.rgraph.net/tests/line/html5-context-menus.html Thu, 17 May 2012 12:00:00 +0000 A new (simple) demo is now available of HTML5 context menus. It greatly simplifies the use of context menus in your page and allows you to integrate them with ease. The demo only works with Firefox (version 12, Windows) currently. http://www.rgraph.net/docs/release-notes-may-2012.html Sun, 15 May 2012 22:00:00 +0000 A new stable version of RGraph is now available. You can read about the changes in the release notes. http://dev.rgraph.net/tests/rose/spinny.html Sun, 13 May 2012 18:00:00 +0000 A new demo is now online that shows how you can use the new RGraph.RotateCanvas(canvas, x, y, angle) method to do just that. In this case producing a rotating chart effect. Note that the angle is measured in RADIANS - not degrees. http://www.rgraph.net Sat, 12 May 2012 14:00:00 +0000 This release has minor miscellantous updates. You can download RGraph at the RGraph website: http://www.rgraph.net Tue, 15 May 2012 17:00:00 +0000 This release has documentation updates, charts involving the use of Math.Pi are now more accurate (ie circular charts), certain smaller functions are now minified by default, tooltips now point to the centre of the relevant shape and the RGraph.Tooltip() function now takes an extra argument (the event object). You can download RGraph at the RGraph website: http://www.rgraph.net/RGraph.minified.zip Sat, 5 May 2012 14:00:00 +0000 This release adds a new minifier - called jsmin - to RGraph. The minified files are used by the front page of the website and they're also available at the link provided. Also a new option for specifying the widths of Donuts has been added - making it easier to nest them. http://www.rgraph.net Wed, 2 May 2012 15:00:00 +0000 A new beta is now available. This beta changes how tooltips look for all chart types. You can see an example on the front page of the RGraph website. As a result of this the expand, contract and snap tooltip effects have been removed. The available effects are 'fade' (the default) and 'none'. Also the Radar chart coords array format has hanged to a single dimensional array. http://dev.rgraph.net Sun, 29 Apr 2012 17:00:00 +0000 The recent HOWTO document showing how to customise the appearance of tooltips and add a small pointer to them will now be the default - so to get the new style you won't have to do anything extra. http://dev.rgraph.net/docs/howto-line-tooltip-override.html Sat, 28 Apr 2012 12:00:00 +0000 A new HOWTO document is now available showing how you can heavily customise the tooltips by using the chart.tooltips.override option. This option allows you to specify a function that completely handles the creation of the tooltips. As a result you have total control over the creation and appearance of your tooltips. The HOWTO also shows you how you can also use the ontooltip event if you're only repositioning the tooltip. http://dev.rgraph.net/docs/howto-line-tooltip-override.html Thu, 26 Apr 2012 18:00:00 +0000 A new HOWTO document is now available showing how you can heavily customise the tooltips by using the chart.tooltips.override option. This option allows you to specify a function that completely handles the creation of the tooltips. As a result you have total control over the creation and appearance of your tooltips. http://www.rgraph.net#download Wed, 25 Apr 2012 17:00:00 +0000 A new beta is now available. This release adds the ability to have "inbar" labels for the Gantt chart, documentation updates and a new OEM license has been introduced. You can download RGraph at the link provided. http://www.rgraph.net#download Wed, 18 Apr 2012 12:00:00 +0000 A new beta version is available. This version adds shortcut functions for creating gradients, a new HOWTO guide for getting a 3D effect, a new Line effect - UnfoldFromCenterTace and the HProgress/VProgress Grow effect now works with grouped progress bars. You can download RGraph at the link provided. http://dev.rgraph.net/tests/line/dual-effect.html Mon, 16 Apr 2012 23:00:00 +0000 A new example of combining the Line chart Trace and UnfoldFromCenter effects to produce a new effect. http://dev.rgraph.net/docs/howto-3d-effect.html Sat, 15 Apr 2012 16:00:00 +0000 A new HOWTO guide is now available for using new CSS 3D transforms which are supported by Firefox, Safari and Chrome. With the new CSS properties you can easily add 3D perspective effects. http://www.rgraph.net#download Thu, 12 Apr 2012 17:00:00 +0000 A new beta version is available. This version adds a few new HOWTO guides and there are other minor documentation updates. You can download RGraph here: http://www.rgraph.net#download ]]> http://www.rgraph.net#download Sat, 7 Apr 2012 16:00:00 +0000 A new beta version is available. This version adds a few new HOWTO guides and includes information on improving the smoothness of the Line chart Trace effect. For the full list of changes read the CHANGELOG and BC files. You can download RGraph here: http://www.rgraph.net#download ]]> http://www.rgraph.net#download Wed, 28 Mar 2012 11:00:00 +0000 A new stable release is now available. This is a very significant release and as such has the RGraph2 moniker. The main new feature is the ability to have multiple charts on one canvas with dynamic features - which is achieved by something called the ObjectRegistry. The other major thing is a move to DOM1 event listeners. This provides better performance which is most noticed with animations and effects. You can read the release notes for this release here: http://www.rgraph.net/docs/release-notes.html ]]> http://www.rgraph.net#download Fri, 23 Mar 2012 12:00:00 +0000 A new beta release is now available. This release adds documentation for the new ObjectRegistry and adds a few new HOWTO guides (including one on using AJAX to update your charts). Thu, 12 Mar 2012 13:00:00 +0000 A new beta release is now available. Notably this release updates the documentation regarding combining charts. You can see this via the docs/combine.html page which contains a combined Bar and Pie chart. The API documentation has also been updated with information about the new ObjectRegistry - the new feature that facilitates the combination of different chart types http://dev.rgraph.net/tests/_misc/zoom.html Thu, 01 Mar 2012 15:00:00 +0000 This is a new example of using the effect of CSS sizing on a canvas to zoom/enlarge it. Normally when sizing your canvas you should use the HTML attributes. Using CSS has the effect of scaling the canvas - not enlarging it. That effect can be turned to our advantage as this example shows. It could be used to facilitate having lots of smaller dials/charts on a page which enlarge when mousing over them. http://dev.rgraph.net/tests/2012-03-25/orange_hbar.html Wed, 22 Feb 2012 17:00:00 +0000 This is an example of replicating a Horizontal Bar chart using RGraph. It uses a few new properties from the beta for the axes and also demonstrates combing charts with tooltips enabled. http://www.rgraph.net Thu, 19 Feb 2012 15:00:00 +0000 A new beta is now available. This beta improves upon the new ObjectRegistry and, notably, separates out some dynamic features (eg tooltips) into a new file - RGraph.core.dynamic.js You will need to include this file if you use tooltips for example. More dynamic features are going to be moved to this file to reduce the size of the core library. The name of the archive has been changed to RGraph2 to try and reinforce how significant a release this is. You can download this new beta at the RGraph website - www.rgraph.net http://dev.rgraph.net/tests/2012-03-25/w3c_events.html Thu, 13 Feb 2012 18:00:00 +0000 A new demonstration of interactive Gauges. This demo shows two Gauge charts on one canvas both with the ability to be independently interactive/adjustable. This demo was made possible by the new ObjectRegistry as well as the Gauge charts .getValue() method. The source code necessary to make this is shown and is less than a page long. http://www.rgraph.net Thu, 09 Feb 2012 10:00:07 +0000 A new beta is now available. This beta changes the way that circular charts calculate their centers and their radius - though you can override this with new properties. It also adds a new method - RGraph.ObjectRegistry.getObjectByXY(e) - which makes it easier to work with the new ObjectRegistry. You can download this new beta at the RGraph website - www.rgraph.net http://www.rgraph.net Sat, 04 Feb 2012 22:59:00 +0000 From this point on Twitter will not be updated any more with news or announcements - only this RSS feed will. http://www.rgraph.net Sat, 04 Feb 2012 21:59:00 +0000 The Gauge chart now has a getValue method which means that you can do things like this: http://dev.rgraph.net/tests/2012-03-25/getvalue_gauge.html http://www.rgraph.net Sat, 04 Feb 2012 15:22:00 +0000 Going forward, the RGraph website will be based on stable releases only. If you wish to look at or use a beta release you will need to download it to your PC or website and use it from there. http://www.rgraph.net Sun, 03 Feb 2012 18:00:07 +0000 A new beta release is now available. Two things are notable: The demo chart on the front page has been updated to take advantage of the new ObjectRegistry by the addition of an animated Pie chart, and also future beta releases will now update the website. So in order for you to see a beta you will need to download it and try it out. http://dev.rgraph.net Sun, 29 Jan 2012 13:40:07 +0000 As an example of the upcoming changes that will allow you to much more easily combine charts the front page Line chart has been updated to include a small Pie chart. As with the Line chart it's animated (using the Grow effect) and also has tooltips. http://dev.rgraph.net http://www.rgraph.net Sun, 28 Jan 2012 14:15:07 +0000 A new beta of RGraph has been released. This release involves big changes in order to allow multiple charts on one canvas with dynamic features. Due to the amount and the significance of changes this release is less stable than previous beta releases, so you're advised not to use this in a production environment. You can see the current set of test pages here: http://dev.rgraph.net/tests/2012-02-25/ http://www.rgraph.net Mon, 23 Jan 2012 13:40:07 +0000 RGraph is currently undergoing significant changes in order to support multiple charts on a single canvas with dynamic features. Currently you can easily have multiple charts on one canvas but when you add dynamic features things begin to break down. This is a significant change to RGraph so it may be some time coming.

At this time two charts have been converted to the new system for tooltips only and you can see these here: http://dev.rgraph.net/tests/2012-02-25/object_registry_thermometer.html
