Heatmap

The heatmap is an additional information layer that can be enabled to visualize numeric data over the graph. It can be enabled by setting the heatMapping function which should provide a numerical value based on the given data. The heat values should lie between 0 and 1.

The heatmap has the following limitations:

• It does not currently work with Safari, as the required SVG filter functionality is not implemented there.
• It is not currently exported or printed.
