A Scatter chart with an offset X axis
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="200">
[No canvas support]
</canvas>
This is the code that generates the chart:
<script>
new RGraph.Scatter({
id: 'cvs',
data: [[15,11], [40,25],[38,23],[312,12],[160,15], [365, 8], [365, -8]],
options: {
backgroundGridHlinesCount: 4,
backgroundGridVlines: false,
backgroundGridBorder: false,
yaxisLabelsCount: 4,
colorsDefault: 'red',
tickmarksStyle: 'circle',
tickmarksSize: 5,
marginLeft: 25,
xaxisScaleMax: 365,
xaxisLabels: ['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec'],
yaxisScaleMin: -15,
yaxisScaleMax: 45,
yaxisTickmarksCount: 4
}
}).draw();
</script>
