polar heatmap

Example on the basics of Polar Heatmap feature.

The Polar Heatmap allows visualizing a 2D matrix of numeric data in a polar coordinate system.
The data is layed out in a grid split to sectors (angle axis) and annuli (amplitude axis).

The most important built-in features are:

  • Fast data and color updates.
  • Bilinear interpolation to smoothly color pixels between data values.

To learn how to extrapolate a heatmap data matrix from a scattered data set, see Polar Sensor Heatmap example
