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

See Documentation on how to use this type here:

The Android Donut Chart Documentation.

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

Donut 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.
