I’m using `fill_z` to color surfaces inside `Shape()` objects. I have a column that has categorical data. But `fill_z` only accepts type float. I mean I can have an additional column with float values, but if I for example only have two cases, using `1.0` and `2.0`, it doesn’t color the two different cases accordingly. Does anyone have a solution to this dilemma?
