WPF Surface 3D Mesh With Contours
// 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.
This WPF 3D chart demo demonstrates how to use the Contour API for SurfaceMesh.
// Source Code
The C#/WPF source code for the WPF Surface 3D Mesh With Contours example is included below (Scroll down!).
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).
The SciChart Examples source code is available on Github and viewable in-app for some platforms
