All Implemented Interfaces:

Styleable, EventTarget

public class PieChart
extends Chart

Displays a PieChart. The chart content is populated by pie slices based on data set on the PieChart.

The clockwise property is set to true by default, which means slices are placed in the clockwise order. The labelsVisible property is used to either display pie slice labels or not.

Since:

JavaFX 2.0
