A graduated blue Gauge chart Gauge chart

This goes in the documents header:

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

Put this where you want the chart to show up:

<canvas id="cvs" width="250" height="250">
    [No canvas support]
</canvas>

This is the code that generates the chart:

<script>
    window.onload = function ()
    {
        var gauge = new RGraph.Gauge({
            id: 'cvs',
            min: 0,
            max: 10,
            value: 7,
            options: {
                backgroundColor: 'Gradient(white:#00a)',
                textColor: 'white',
                tickmarksBigColor: 'white',
                tickmarksSmallColor: 'white',
                redColor: 'rgba(0,0,0,0)',
                yellowColor: 'rgba(0,0,0,0)',
                borderInner: '#00c',
                borderOuter: 'Gradient(blue:blue:blue:blue:blue:blue:blue:blue:blue:blue:blue:blue:blue:blue:blue:blue:blue:blue:black)',
                adjustable: true,
                textAccessible: true
            }
        }).draw();
    };
</script>
