totalcross.ui.chart.PieChart

public class PieChart
extends Chart

A simple pie chart.

The values do not have to be in percentage; the percentage is computed based on the series values. If the user clicks on the slice, a popup shows the corresponding value. By setting the legendValueSuffix to "%", the value displayed will be the percentage instead of the serie's value.
