Demonstrates how to use FastUniformHeatmapRenderableSeries and create a real-time Heatmap in SciChart for Android.

Android Heatmap Charts can be used to visualize 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 FastUniformHeatmapRenderableSeries requires an UniformHeatmapDataSeries, which contains 1D array with heatmap values and ColorMap instance which allows to map values to colors.

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


You can enable drawing of heatmap value inside each cell by calling setDrawTextInCell(True)
