An example of a RScatter chart with an interactive key

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="500" height="450">
    [No canvas support]
</canvas>

This is the code that generates the chart:

<script>
    window.onload = function ()
    {

        var data1 = [[45,51,'green'],[45,46,'green'],[45,35,'green']];
        var data2 = [[225,32,'red'],[225,25,'red'],[225,12,'red']];
        var data3 = [[315,13,'pink'],[315,26,'pink'],[315,36,'pink']];

        var rscatter = new RGraph.RScatter({
            id: 'cvs',
            data: [data1, data2, data3],
            options: {
                key: ['Richard','Dave','Charles'],
                keyInteractive: true,
                keyColors: ['green','red','pink'],
                keyMargin: 5,
                keyLabelsAxes: 'n',
                textAccessible: true
            }
        }).draw();
    };
</script>
