We are pleased to announce that the SciChart WPF v6.3 build 13476, has now been released! This update includes a number of bug fixes and minor enhancements requested by users since version 6.2.x. This release is a drop-in replacement for 6.x and it is recommended for all users to update.
What’s New in SciChart v6.3?
1) .NET 5 Support
SciChart WPF library has been tested to work in .NET 5 applications! Please also note that SciChart WPF Library has upgraded to NetCore 3.1.
2) Heatmap Peak detector Feature
This is a new feature requested by many customers of SciChart WPF. When a heatmap dimension exceeds the corresponding screen dimension the peaks can be lost because of the heatmap compression, so it becomes important to find and show those.
The Heatmap Peak Detector example demonstrates how to create a WPF 2D Uniform Heatmap and use Automatic Peak Detection to highlight the peaks.
Simply setting the AutoPeakDetection property on a FastUniformHeatmapRenderableSeries in SciChart turns on peak detection algorithm.
The Audio Analyzer demo showcases realtime charts that use computer microphone.
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 in form of the column chart on the lower left side and the spectrogram, created with heatmap on the right.
SciChart API is designed to be very flexible. You can customize every element of the chart to your needs. We have created an example that demonstrates how to customize axis labels individually with the LabelProviderAPI.
Using this API, you can override individual labels for all types of axes.
