An offset X axis Line chart
This goes in the documents header:
<script src="RGraph.common.core.js"></script>
<script src="RGraph.line.js"></script>
Put this where you want the chart to show up:
<canvas id="cvs" width="600" height="250">
[No canvas support]
</canvas>
This is the code that generates the chart:
<script>
new RGraph.Line({
id: 'cvs',
data: [19,13,5,-4,-6,-1,3],
options: {
hmargin: 10,
marginBottom: 125,
linewidth: 2,
backgroundGridHlinesCount: 6,
yaxisLabelsCount: 3,
colors: ['gray'],
yaxisScaleMax: 20,
yaxisScaleMin: -10,
yaxisTickmarksCount: 3,
yaxisScaleUnitsPost: '% ',
marginLeft: 50,
xaxisLabels: ['Carl','Vera','Hoolio','Indigo','Pete','Louise','Jim']
}
}).draw();
</script>
