WPF Polar Chart
// 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.
You can use our WPF chart library to generate a simple polar chart. Demonstrates how to define polar chart with line series.
The Polar Chart is not defined by a series, but actually a special Polar Axis type. Most of the SciChart RenderableSeries have been converted to work with Polar Charts.
Tips!
You can change AxisAlignment of XAxis and YAxis. You can also change the YAxis Angle using slider at the top.
