An example of a Radar chart with an interactive key

The interactive key has been re-implemented as of June 2013 and added to more chart types.

[No canvas support]

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.radar.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 radar = new RGraph.Radar({
            id: 'cvs',
            data: [
                [5,6,3,5,4,5],
                [8,6,7,8,9,9,6]
            ],
            options: {
                colors: ['rgba(0,0,0,0)'],
                strokestyle: ['red', 'black'],
                linewidth: 3,
                key: ['Richard','Dave'],
                keyColors: ['red', 'black'],
                keyInteractive: true
            }
        }).draw();
    };
</script>
