This example of three donut charts shows how they can be nested inside each other.
This goes in the documents header:<script src="RGraph.common.core.js"></script> <script src="RGraph.pie.js"></script>Put this where you want the chart to show up:
<canvas id="cvs" width="550" height="550">
[No canvas support]
</canvas>
This is the code that generates the chart:
<script>
window.onload = function ()
{
var pie1 = new RGraph.Pie({
id: 'cvs',
data: [4,3,5,6,8],
options: {
variant: 'donut',
variantDonutWidth: 50,
strokestyle: 'white',
linewidth: 5,
gutterLeft: 15,
gutterRight: 15,
gutterTop: 15,
gutterBottom: 15,
shadowBlur: 25,
shadowOffsetx: 0,
shadowOffsety: 0
}
}).draw()
var pie2 = new RGraph.Pie({
id: 'cvs',
data: [5,4,8,6,2],
options: {
radius: pie1.radius - 50,
variant: 'donut',
variantDonutWidth: 50,
strokestyle: 'white',
linewidth: 5,
shadow: false
}
}).draw()
var pie3 = new RGraph.Pie({
id: 'cvs',
data: [4,1,5,6,3],
options: {
radius: pie2.radius - 50,
variant: 'donut',
variantDonutWidth: 50,
strokestyle: 'white',
linewidth: 5,
shadowBlur: 25,
shadowOffsetx: 0,
shadowOffsety: 0
}
}).draw()
RGraph.ObjectRegistry.bringToFront(pie2);
};
</script>
