A dual-scale Thermometer chart
This goes in the documents header:
<script src="RGraph.common.core.js"></script>
<script src="RGraph.drawing.yaxis.js"></script>
<script src="RGraph.bar.js"></script>
Put this where you want the chart to show up:
<canvas id="cvs" width="100" height="400">
[No canvas support]
</canvas>
This is the code that generates the chart:
<script>
thermometer = new RGraph.Thermometer({
id: 'cvs',
min: 0,
max: 20,
value: 8,
options: {
scaleVisible: true,
marginLeft: 25
}
}).grow();
coords = thermometer.coords;
yaxis = new RGraph.Drawing.YAxis({
id: 'cvs',
x: coords[0][0],
options: {
marginTop: thermometer.bulbTopCentery,
marginBottom: thermometer.canvas.height - (coords[0][1] + coords[0][3]),
yaxis: false,
textColor: 'red',
yaxisScaleMax: 100,
yaxisScaleMin: 80
}
}).draw();
</script>
