Question: is their any way to provide our own custom tool tips for HeatMap?

[hmf]

I need to show for each discrete element of a HeatMap additional information that is not appearing in the tool tip. Is there anyway I can override this so that I can show more information based on the (X,Y) and data values?

I have looked at the source but cannot see how to do this. The Chart<ST extends Styler, S extends Series> does not seem to have code related to the tool tips.

TIA
