How to display values with in piechart using Jfreechart(values in sector )

I am using Jfreechart to create pie charts. Values are displayed outside pie chart as labels. I want to display the values within the pie sectors only. How can i achieve this. Please can any one help me.

Thanks in advance

 

Use setSimpleLabels(), as shown below; org.jfree.chart.demo.PieChartDemo1 is a good starting point.

PiePlot plot = (PiePlot) chart.getPlot();
plot.setSimpleLabels(true);
