The chart is using dates as X values.
This goes in the documents header:<script src="RGraph.common.core.js"></script> <script src="RGraph.scatter.js"></script>Put this where you want the chart to show up:
<canvas id="cvs" width="600" height="400"> [No canvas support] </canvas>This is the code that generates the chart:
<script> data1 = [['2013-01-01',50,'green'],['2013-02-01',10,'green'],['2013-11-31',35,'green'],['2013-12-31',25,'green']]; data2 = [['2013-03-31',54,'red'],['2013-06-06',45,'red'],['2013-04-06',13,'red'],['2013-08-23',32,'red']]; scatter = new RGraph.Scatter({ id: 'cvs', data: [data1,data2], options: { line: true, xaxisScaleMin: '1 January 2013', xaxisScaleMax: '2013-12-31', xaxisLabels: ['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec'] } }).draw(); </script>
