Demonstrates how to create a real-time iOS Heatmap using SciChart. See Documentation on how to use this type here: The iOS Heatmap Chart Documentation.

iOS Heatmap Charts can be used to visualise a variety of scientific and statistical data. Display a real-time spectrogram (Fourier Transform plus Time) of audio data. To overlay areas of heat on a background image such as a map or image, or to quickly bring to life 2-dimensional data and show the relative intensities via the heat color.

The SCIFastUniformHeatmapRenderableSeries expects a 2D Array of data in the form of a SCIUniformHeatmapDataSeries and has a user-defined colour map which can be displayed as a legend over the chart.

In this example you can tap and drag on the chart to see the animated-zoom performance while the heatmap is updating.

The Swift and Objective-C source code for the iOS and macOS Heatmap Chart example is included below (Scroll down!).
