Heatmap inside custom 2d geometry shape

Hi,

I have a specific 2d geometry of an object with multiple fields. I also know the data values for each field. How can I plot a heatmap with my values inside the fileds using the shape of my 2d object. I could get the CAD of the object for example, create a smiple drawing myself, or imitate my 2d shape with blocks or somehow else ....

Thanks.

Are you saying you just want to make a heat map with a nonrectangular mask?
