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.

The Audio Analyzer demo showcases realtime charts that use computer microphone in an MVVM code example.

At a refresh rate of up to 100 Hz the example receives audio data and creates a waveform of the sounds, that you can see in the top chart.

The example next converts the audio data to a frequency domain using a Radix-2FFT and updates the screen with the result. There is a Fourier transform done with the help of the column chart on the lower left side and the spectrogram, created with heatmap on the right.

This showcases how SciChart can be used for spectral analysis, visualizing scientific data from data-acquisition devices, audio spectra, or radio frequency.

The C#/WPF source code for the WPF Audio Analyzer example is included below (Scroll down!).
