Vaadin Charts Stacked Percentage Column and HeatMap configuration

Good day,

I’m currently evaluating some requirements (we are currently working with charts 3.0) for our project and I am lacking info:

Using Heat Map, is there a way not to use gradual color change and instead switch colors sharply based on specific set limits - say if the number is between 0 and 33 use green, 33 - 66 use yellow, 66-100 use red.

I would be happy with some directions where to look if not the answers.


Edit: solved my stacked column problem.
