   Hi I am displaying percentages in item lables of a PIE chart and it is rounding up. I actually want to be able to display the item lable percentage in 2 decimal places. Can you please advise how to do this? Many Thanks

   Additionally I am using the following code:

   plot.setLabelGenerator(new StandardPieSectionLabelGenerator("{2}{0}"));

   I believe there is additional code that can be appended to the above 'new DecimalFormat("0.00%")) but this doesn't seem to work.

   Tom,
   Please try the below code in the java script. NOTE: There are two new import statements import java.text.numberformat and ..decimalformat.

   //-----------
   //import the necessary classes
   import org.jfree.chart.JFreeChart;
   import org.jfree.chart.plot.PiePlot;
   import org.jfree.chart.labels.StandardPieSectionLabelGenerator;
   import java.text.NumberFormat;
   import java.text.DecimalFormat;

   plot =((PiePlot) chart.getPlot());
   plot.setForegroundAlpha(0.5f);

   //chart.setBackgroundPaint(new GradientPaint(0,0,Color.gray.brighter().brighter(),0,displayFrame.getHeight(), Color.LIGHT_GRAY));

   float h = displayFrame.getHeight();
   float w = displayFrame.getWidth();
   GradientPaint gradientPaint = new GradientPaint(0.0F, 10.0F, Color.white, 0, h, Color.orange);
   // plot.setBackgroundPaint(gradientPaint);
   chart.getTitle().setPaint(Color.blue);

   plot.setLabelGenerator(

   new StandardPieSectionLabelGenerator(
   "{0}={2}",
   new DecimalFormat("#,##0"),
   new DecimalFormat("0.0%"))
   );

   //-----------
