How to display values within pie chart sector

I am using JFreeChart to create pie charts. Values are displayed outside pie chart sec开发者_C百科tors as labels. I want to display the values within the pie sectors. How can I achieve this. Please can any one help me?

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

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

If you are using createPieChart3D to create Pie chart, following URL will be helpful to you.

What I know is, showing values inside is default feature of the chart. If you're unable to do so it seems that you have changed the default way.
