You can read about the changes in the release notes: http://www.rgraph.net/docs/release-notes-may-2012.html ]]> 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 ]]> 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 ]]> http://www.rgraph.net 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: http://www.rgraph.net/RGraph.minified.zip ]]> 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 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
http://dev.rgraph.net/tests/2012-02-25/object_registry_waterfall.html http://www.rgraph.net/docs/release-notes-january-2012.html Fri, 13 Jan 2012 14:40:07 +0000 A new stable release of RGraph is now available. Notably it greatly simplifies event handling. You can read more detail in the release notes. http://www.rgraph.net Fri, 06 Jan 2012 14:40:07 +0000 A new beta of RGraph has been released. Bug fixes and a change to the ModalDialog so that it is now (re)created every time it is shown and not cached. http://www.rgraph.net Fri, 30 Dec 2011 13:40:07 +0000 A new beta of RGraph has been released. The test area is undergoing a revamp. If you would like your chart added, please email it to the support address. For an example of how it should be, have a look at the current tests: http://dev.rgraph.net/tests http://www.rgraph.net Sun, 18 Dec 2011 16:01:07 +0000 A new beta of RGraph has been released. New background properties, a few new HOWTO guides, documentation updates, new Conceal effect
