This example demonstrates how to create an Android Pie Chart in code.

See Documentation on how to use this type here:

The Android Pie Chart Documentation.

The SciPieChartSurface can be used to render either Pie, Donut or Nested Pie charts in Java.

Pie charts can be animated on show, have legends and support selection of segments, as well as showing and hiding of labels. Data is provided by a number of PieSegments, which are stored in a IPieRenderableSeries.
