This example shows animated segment separation. This used to be something that had to be done seperately, however now it's built into the Pie chart as a tooltip effect. You can utilise the effect by using the chart.highlight.style setting like this:
<script>
window.onload = function ()
{
var pie = new RGraph.Pie('cvs', [24,43,51,16,26,23,35]);
pie.Set('chart.strokestyle', 'rgba(0,0,0,0)');
pie.Set('chart.labels', ['Richard','John','Kev','Lou','Pete','Fred','Bob']);
pie.Set('chart.tooltips', ['Richard','John','Kev','Lou','Pete','Fred','Bob']);
pie.Set('chart.highlight.style', 'explode');
pie.Set('chart.labels.sticks', true);
pie.Set('chart.radius', 100);
pie.Draw();
}
</script>
