This Pie chart is similar to an old Pie chart demo. But instead of using the onclick event this uses the onmousemove event.
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]
</canvas>
This is the code that generates the chart:
<script>
window.onload = function ()
{
// 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'],
labelsSticksList: true,
textColor: '#ccc',
exploded: 5,
radius: 100,
linewidth: 1,
shadowBlur: 10,
shadowColor: '#ccc',
textAccessible: true
}
}).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';
e.stopPropagation();
}).draw()
// Add the window click listener that resets the Pie chart
window.onclick = function (e)
{
pie.set('exploded', 5);
RGraph.redraw();
}
};
</script>
