# Class PieChart

java.lang.Object
javafx.scene.Node
javafx.scene.Parent
javafx.scene.layout.Region
javafx.scene.chart.Chart
javafx.scene.chart.PieChart

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
