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.
As well as creating a Heatmap chart with SciChart 2D, you can also create one using the SciChart3DSurface.
This is achieved by using a SurfaceMeshRenderableSeries3D with UniformGridDataSeries3D and by using a CameraController with ProjectionMode = Orthogonal. The result is the camera looks top-down and can view the surface-mesh as a flat Heatmap.
Tip!
The Heatmap can also be scrolled by pushing data to the the UniformGridDataSeries3D.PushRow method.

Did you know you can also view the source code from one of the following sources as well?
- Clone the SciChart.WPF.Examples from Github.
- Or, view source in the SciChart WPF Examples suite.
- Also the SciChart WPF Trial contains the full source for the examples (link below).
