Hi Baiss,
All you should have to do is just add a ERPPieChart component to your WOComponent, eg
MyChart : ERPPieChart {
name = "Monthly Totals";
items = myArray;
nameKey = "name";
valueKey = "amount";
chartType = "PieChart";
}
You can gain a fair bit of flexibility with the "configuration" binding, and also you can use the "chart" binding on it's own if you already have a JFreeChart and just want a nice way to include it in your component.
Cheers,
Sharpy
