// 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.

DOWNLOAD THE SDK

// WPF Heatmap Metadata Chart

Demonstrates how to create a Heatmap with Text in the cells SciChart. Accepts a 2D Array of data and has a user-defined colour map which can be displayed as a legend over the chart.
