Class PieData

java.lang.Object

com.github.mikephil.charting.data.ChartData<PieDataSet>

com.github.mikephil.charting.data.PieData

public class PieData
extends ChartData<PieDataSet>

A PieData object can only represent one DataSet. Unlike all other charts, the legend labels of the PieChart are created from the x-values array, and not from the DataSet labels. Each PieData object can only represent one PieDataSet (multiple PieDataSets inside a single PieChart are not possible).
