A basic example of the drawing API image object

[No canvas support]

This goes in the documents header:
<script src="RGraph.common.core.js"></script>
<script src="RGraph.common.dynamic.js"></script>
<script src="RGraph.common.tooltips.js"></script>
<script src="RGraph.drawing.image.js"></script>
<script src="RGraph.line.js"></script>
Put this where you want the chart to show up:
<canvas id="cvs" width="600" height="250">
    [No canvas support]
</canvas>
This is the code that generates the chart:
<script>
    var line = new RGraph.Line({
        id: 'cvs',
        data: [5,4,8,4,3,5,2],
        options: {
            hmargin: 5,
            xaxisLabels: ['Monday','Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday'],
            backgroundGridVlines: false,
            backgroundGridBorder: false,
            tickmarksStyle: 'circle',
            tickmarksSize: 7
        }
    }).draw();
    
    var coords = line.coords[2];
    
    var img = new RGraph.Drawing.Image({
        id: 'cvs',
        x: coords[0],
        y: coords[1],
        src: '../images/logo.png',
        options: {
            halign: 'center',
            valign: 'center',
            alpha: 0.6,
            tooltips: ['The tooltip!']
        }
    }).draw();
</script>
