Explode when clicked

This demo shows a pie chart that has two expanding segments when clicked.

This goes in the documents header:

<script src="RGraph.common.core.js"></script>
<script src="RGraph.common.tooltips.js"></script>
<script src="RGraph.common.dynamic.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="480" height="250">
    [No canvas support]
</canvas>

This is the code that generates the chart:

<script>
    window.onload = function ()
    {
        /**
        * Create the Pie chart as normal
        */
        var pie = new RGraph.Pie({
            id: 'cvs',
            data: [8,6,5,3,5],
            options: {
                linewidth: 1,
                shadow: true,
                labels: ['Bob',,,'Jerry'],
                labelsSticksList: true,
                textAccessible: true
            }
        }).draw()



        /**
        * Add the event listener fnctions using the new dollar syntax. This handles the click
        * for the first and fourh segments
        */
        pie.$3.onclick =
        pie.$0.onclick = function (e, shape)
        {
            var obj = shape['object'];
            obj.set('exploded', []);
            obj.explodeSegment(shape['index'], 15);
        }

        /**
        * Add the event listener fnctions using the new dollar syntax. This handles the mousemove
        * for the first and fourh segments
        */
        pie.$3.onmousemove =
        pie.$0.onmousemove = function (e, shape)
        {
            return true;
        }


        /**
        * This function "resets" the pie before the above two functions fire. Note that the event is registered to
        * use the capture phase of click event so that it will fire before the above two $ events.
        */
        window.addEventListener('click', function (e)
        {
            pie.set('exploded', []);
            RGraph.redraw();
        }, true);
    };
</script>
