Past release notes

August 2019 (v5.02)

The RGraph.path() function (formerly the RGraph.path2() function) has been updated so it now works in any of the following configurations:

// Single argument (preferred usage)
RGraph.path({
    object: myObject,
    path:   'b r % % % % f %',
    args:   [150,150,50,50,'red']
});

// Single argument passing the context instead of the object
RGraph.path({
    context: myObject.context,
    path:   'b r % % % % f %',
    args:   [250,150,50,50,'red']
});

// Multiple arguments using the object
RGraph.path(
    myObject,
    'b r % % % % f %',
    350,150,50,50,'red'
);

// Multiple arguments using the context
RGraph.path(
    myObject.context,
    'b r % % % % f %',
    450,150,50,50,'red'
);

Going forward the first is the preferred usage mode.

Like the canvas String.format() function the SVG version can now also use the %[number] format instead of the {[number]} format. So it could look like this: 'Some example text: %1 {2} %3 %2'.format('red', 'orange','yellow') The output would be this: Some example text: red orange yellow orange
The Horseshoe meter example for the Pie chart has now been converted to a dedicated class so it's far easier to use. The example is here if you want to view it: https://www.rgraph.net/demos/pie-horseshoe.html And there's a note in the documentation here.
Fixed a bug in the canvas RGraph.parseDate() function that presented itself when you used the date format 2012-12-31T20:23:56
Added xaxisLabelsAngle to the drawing API X axis object for both labels and scales.
Added the Drawing API X axis xaxisLabelsOffsetx and xaxisLabelsOffsety properties.
Added the Drawing API Y axis yaxisLabelsOffsetx and yaxisLabelsOffsety properties.
Added two needle head properties to the Meter chart that will help you control the appearance of the needle head: needleHeadWidth and needleHeadLength

The RGraph.text() function (also known as the RGraph.text2() function) can now take just a single argument - like this:

RGraph.text({
    object: bar,
    x:      50,
    y:      50,
    bold:   false,
    italic: false,
    text:   'Some custom text'
});

Added the RGraph.SVG.text.defaults object. This acts precisely like the canvas RGraph.text.defaults object described below but applies to RGraph.SVG.text() function.
Added the RGraph.text.defaults object. With this you can set default values which are then used by the RGraph.text() function. For example:
```
RGraph.text.defaults.bold = true;
RGraph.text.defaults.font = 'Verdana';
RGraph.text.defaults.size = 18;
```
This object is for when you're adding text to your charts by using the RGraph.text() function yourself - not so much the text that's added by RGraph in the process of creating charts.
The String.format() function now supports a syntax more like the classic C function printf(). For example:
```
str = 'The %1 brown fox jumps over %2 lazy dog. Yes %1!';
str = str.format('quick', 'the');
alert(str);
```
Some of the demos that are in the download archive didn't include the core library in the page so they didn't work offline. This has been fixed so all the demos should now work offline.
Made a change to the SVG Line charts so that if you have two (or more) datasets and view the tooltip with the same index on one line then the other the tooltips appear as you'd expect. They previously required you to click first to clear the tooltip.
It shouldn't affect you - but I've added RGraph.text() as an alias to the RGraph.text2() function. In the same vein I've also added RGraph.path() which is an alias of the RGraph.path2() function.
Documented the missing needleHead Meter chart property.
The canvas Rose chart obj.data_seq property was added. This is a sequential representation of the data (ie a flattened version of the data).
The canvas Rose chart strokes are now redrawn if the linewidth is greater than one. This means that the strokes will appear above any fill color. This has been changed for regular, stacked and non-equi-angular variations of the chart.
