# 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>
