SciChart® the market leader in Fast WPF Charts, WPF 3D Charts, iOS Chart, Android Chart and JavaScript Chart Components
SciChart Android ships with ~90Â Android Chart Examples which you can browse, play with, view the source-code and even export each SciChart Android Chart Example to a stand-alone Android Studio project. All of this is possible with the new and improved SciChart Android Examples Suite, which ships as part of our Android Charts SDK.
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.
The full source code for the Android Donut Chart example is included below (Scroll down!).
