Build your own label format using StandardPieItemLabelGenerator and forward it to the PiePlot:

Code: Select all

PiePlot plot = (PiePlot) chart.getPlot();
PieSectionLabelGenerator gen = new StandardPieItemLabelGenerator("{0}={2}%");
plot.setLabelGenerator(gen);

I guess you could use the setLegendLabelGenerator method of the plot in the same way.

As written previously:

setLabelGenerator for lthe pie section label
setLegendLabelGenerator for the legend

build the format you need for each of them using StandardPieItemLabelGenerator class (different format if you want different label)
