  extended by org.jfree.chart.plot.Plot
      extended by org.jfree.chart.plot.PiePlot
All Implemented Interfaces:
java.io.Serializable, java.lang.Cloneable, java.util.EventListener, AxisChangeListener, MarkerChangeListener, LegendItemSource, DatasetChangeListener, org.jfree.util.PublicCloneable
Direct Known Subclasses:
PiePlot3D, RingPlot

public class PiePlot
extends Plot
implements java.lang.Cloneable, java.io.Serializable

A plot that displays data in the form of a pie chart, using data from any class that implements the PieDataset interface. The example shown here is generated by the PieChartDemo2.java program included in the JFreeChart Demo Collection:

PiePlotSample.png

Special notes:

  1. the default starting point is 12 o'clock and the pie sections proceed in a clockwise direction, but these settings can be changed;
  2. negative values in the dataset are ignored;
  3. there are utility methods for creating a PieDataset from a CategoryDataset;

setSectionPaint

public void setSectionPaint(java.awt.Paint paint)
Deprecated. Use setSectionPaint(Comparable, Paint) and setBaseSectionPaint(Paint). Deprecated as of version 1.0.6.
