A Pie chart using dollar syntax for events

This is a Pie chart that uses dollar syntax to attach a custom click event handler to the third segment.

[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.pie.js"></script>
Put this where you want the chart to show up:
<canvas id="cvs" width="450" height="250">
    [No canvas support]
</canvas>
This is the code that generates the chart:
<script>
    window.onload = function ()
    {
        var pie = new RGraph.Pie({
            id: 'cvs',
            data: [4,8,4,6,5,3,2,5],
            options: {
                labelsSticksList: true,
                labels: ['Alvin','Pete','Hoolio','Jack','Kev','Luis','Lou','Jesse'],
                textAccessible: true
            }
        }).draw();
        
        pie.$2.onclick = function (e, shape)
        {
            alert('The segment was clicked!');
        }
        
        pie.$2.onmousemove = function (e, shape)
        {
            return true;
        }
    };
</script>
