// WPF Chart Examples
SciChart WPF ships with hundreds of WPF Chart Examples which you can browse, play with, view the source-code and even export each WPF Chart Example to a stand-alone Visual Studio solution. All of this is possible with the new and improved SciChart WPF Examples Suite, which ships as part of the SciChart WPF SDK.
Generates polar charts with all supported annotation types.
Note! Polar Chart currently does not support HorizontalLineAnnotation and VerticalLineAnnotation.
