A Meter chart customised to look a bit like the Google charts Meter

This goes in the documents header:

<script src="RGraph.common.core.js"></script>
<script src="RGraph.common.dynamic.js"></script>
<script src="RGraph.meter.js"></script>

Put this where you want the chart to show up:

<canvas id="cvs" width="600" height="250" style="border-radius: 15px">
    [No canvas support]
</canvas>

This is the code that generates the chart:

<script>
    window.onload = function ()
    {
        var meter = new RGraph.Meter({
            id: 'cvs',
            min: 0,
            max: 100,
            value: 75,
            options: {
                centerpinStroke: 'rgba(0,0,0,0)',
                centerpinFill: 'rgba(0,0,0,0)',
                colorsRanges: [
                    [0,10,'#f20'],
                    [10,20,'#f30'],
                    [20,30,'#f50'],
                    [30,40,'#f60'],
                    [40,50,'#f80'],
                    [50,60,'#fa0'],
                    [60,70,'#fc0'],
                    [70,80,'#fd0'],
                    [80,90,'#ff0'],
                    [90,100,'#ff0'],
                ],
                labelsCount: 0,
                anglesStart: RGraph.PI + 0.5,
                anglesEnd: RGraph.TWOPI - 0.5,
                linewidthSegments: 0,
                textSize: 16,
                strokestyle: 'white',
                segmentRadiusStart: 150,
                needleRadius: 210,
                border: 0,
                tickmarksSmallNum: 0,
                tickmarksBigNum: 0,
                adjustable: true
            }
        }).draw()
    };
</script>
