RGraph: HTML5 canvas graph library - Thermometer chart documentation
The thermometer chart, along with the progress bar, is a prime candidate for use in a status panel. Much like the progress bar,
but the design may be better suited to your application/website etc.
The example file is here.
<script>
window.onload = function ()
{
var thermometer = new RGraph.Thermometer('myCanvas', data);
thermometer.Set('chart.gutter', 45);
thermometer.Set('chart.colors', ['rgba(255,0,0,1)']);
thermometer.Draw();
}
</script>
