The interactive key has been re-implemented as of June 2013 and added to more chart types.
This goes in the documents header:<script src="RGraph.common.core.js"></script> <script src="RGraph.common.dynamic.js"></script> <script src="RGraph.common.key.js"></script> <script src="RGraph.drawing.rect.js"></script> <script src="RGraph.bar.js"></script>Put this where you want the chart to show up:
<canvas id="cvs" width="450" height="300">
[No canvas support]
</canvas>
This is the code that generates the chart:
<script>
window.onload = function ()
{
var rose = new RGraph.Rose({
id: 'cvs',
data: [
[3,2,5],
[4,5,3],
[5,6,4],
[1,8,5],
[4,5,3]
],
options: {
textAccessible: true,
key: ['Richard','Dave','Charles'],
keyInteractive: true,
margin: 5,
labelsAxes: []
}
}).draw();
};
</script>
