A basic example of the drawing API circle object

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>
    var line = new RGraph.Line({
        id: 'cvs',
        data: [5,8,6,4,3,5,2],
        options: {
            hmargin: 5,
            labels: ['Monday','Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday'],
            textAccessible: true
        }
    }).draw();
    
    var coords = line.coords[2];
    
    var circle = new RGraph.Drawing.Circle({
        id: 'cvs',
        x: coords[0],
        y: coords[1],
        radius: 30,
        options: {
            strokestyle: 'rgba(0,0,0,1)',
            fillstyle: 'rgba(0,0,0,0.2)'
        }
    }).on('click', function (e, shape)
    {
        alert('[RGRAPH] The circle has been clicked!');

    }).on('mousemove', function (e, shape)
    {
        return true;
    }).draw();
</script>
