All Implemented Interfaces:

Serializable, Cloneable, EventListener, AnnotationChangeListener, AxisChangeListener, MarkerChangeListener, LegendItemSource, DatasetChangeListener, org.jfree.util.PublicCloneable

Direct Known Subclasses:

PiePlot3D, RingPlot
```
public class PiePlot
extends Plot
implements Cloneable, 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:

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;
