WPF Chart Realtime FFT Spectrum Analyzer

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

The Spectrum Analyzer Demo showcases a real-time frequency domain chart with cursors and axis drag interactivity in an MVVM code example.

At a refresh rate of 50Hz the example computes a random fourier series and transforms using a Radix-2 FFT, before updating the screen with the result.

A shader effect is used to provide a slight glow to the series to simulate the trace glow on an oscilloscope VDU.
