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.scatter.js"></script>Put this where you want the chart to show up:
<canvas id="cvs" width="450" height="350">
[No canvas support]
</canvas>
This is the code that generates the chart:
<script>
var data1 = [[45,51,'green'],[45,46,'green'],[45,35,'green']],
data2 = [[225,32,'red'],[225,25,'red'],[225,12,'red']],
data3 = [[315,13,'pink'],[315,26,'pink'],[315,36,'pink']];
new RGraph.Scatter({
id: 'cvs',
data: [data1, data2, data3],
options: {
xmax: 360,
labels: ['Q1','Q2','Q3','Q4'],
key: ['Richard','Dave','Charles'],
keyPosition: 'gutter',
keyInteractive: true,
keyColors: ['green','red','pink']
}
}).draw();
</script>
