A basic example of the drawing API circle 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.circle.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>
    line = new RGraph.Line({
        id: 'cvs',
        data: [5,8,6,4,3,5,2],
        options: {
            hmargin: 5,
            xaxisLabels: ['Monday','Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday']
        }
    }).draw();
    
    coords = line.coords[2];
    
    circle = new RGraph.Drawing.Circle({
        id: 'cvs',
        x: coords[0],
        y: coords[1],
        radius: 30,
        options: {
            colorsStroke: 'black',
            colorsFill: 'red',
            linewidth: 3,
            tooltips: ['Hurrah!']
        }
    }).draw();
</script>
