JavaScript Polar Heatmap Chart
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
