An Odometer chart using a background image

[No canvas support]

This goes in the documents header:
<script src="RGraph.common.core.js"></script>
<script src="RGraph.drawing.image.js"></script>
<script src="RGraph.bar.js"></script>
Put this where you want the chart to show up:
<canvas id="cvs" width="300" height="300">
    [No canvas support]
</canvas>
This is the code that generates the chart:
<script>
    new RGraph.Drawing.Image({
        id: 'cvs',
        x: -4,
        y: 0,
        src: '../images/odometer-background.png'
    }).draw();
    
    new RGraph.Odometer({
        id: 'cvs',
        min: 0,
        max: 360,
        value: 56,
        options: {
            colorsGreenColor: 'rgba(0,0,0,0)',
            colorsYellowColor: 'rgba(0,0,0,0)',
            colorsRedColor: 'rgba(0,0,0,0)',
            colorsBackground: 'rgba(0,0,0,0)',
            backgroundBorder: 'rgba(0,0,0,0)',
            backgroundLinesColor: 'rgba(0,0,0,0)',
            tickmarks: false,
            tickmarksLargeColor: 'rgba(0,0,0,0)',
            textColor: 'rgba(0,0,0,0)',
            needleColor: '#ddd',
            needleTail: false,
            needleHead: false,
            needleThickness: 5   
        }
    }).draw();
</script>
