Pie chart explode (onmousemove)

This Pie chart is similar to an old Pie chart demo. But instead of using the click event this uses the mousemove event.

[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.common.effects.js"></script>
<script src="RGraph.pie.js"></script>
Put this where you want the chart to show up:
<canvas id="cvs" width="450" height="300">
    [No canvas support]
This is the code that generates the chart:
    // Create the Pie chart
    pie = new RGraph.Pie({
        id: 'cvs',
        data: [4,6,3,5,2,5,8],
        options: {
            labels: ['Monday', 'Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday'],
            textColor: '#ccc',
            exploded: 5,
            radius: 100,
            linewidth: 1,
            shadowBlur: 10,
            shadowColor: '#ccc'
    }).on('mousemove', function (e, shape)
        var idx = shape['index'];
        if (typeof(pie.Get('exploded')) == 'number' || pie.Get('exploded')[idx] <= 5) {
            pie.set('exploded', 5)
            pie.explodeSegment(idx, 25);
        e.target.style.cursor = 'pointer';
    // Add the window click listener that resets the Pie chart
    window.onclick = function (e)
        pie.set('exploded', 5);
