WPF Chart Custom Point Marker

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.

Demonstrates two different methods of creating Custom PointMarkers in SciChart:

#1 By inheriting BasePointMarker

Using this method, you can inherit BasePointMarker and override Draw. The Draw method is called for every single point which is on-screen in your DataSeries. Use the RenderContext API to do the drawing.

#2 By inheriting BitmapSpriteBase

Using this method, you can inherit BitmapSpriteBase and override RenderToCache. The RenderToCache method is called once and allows you to cache a single marker using the RenderContext API. This method is far faster but all markers must look the same.

Note: There is also another method, by using SpritePointMarker. This method allows you to cache a WPF UIElement to bitmap and repeatedly draw.
