A basic Thermometer chart

This goes in the documents header:

<script src="RGraph.common.core.js"></script>
<script src="RGraph.thermometer.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>
    new RGraph.Thermometer({
        id: 'cvs',
        min: -10,
        max: 40,
        value: 7,
        options: {
            scaleVisible: true
        }
    }).draw();
</script>
