I would like to draw a TF2 function f(x,y). The problem is that the function values spread over a huge range. My goal is to restrict the drawing range in z to a certain interval, completely analog to

sorry, I don’t know how, this function interpolates a table, so there is a lot of stuff that I would need to provide you with. I will try to work around this display problem somehow.

I worked around it by creating a histogramm, filling it by evaluating the function and drawing it. It don’t understand what the problem was, so it’s hard to reproduce it.
I had set the Canvas to log-log but worked in normal scale, so I had really tiny values. Now it do everything really in log-log, I assume it is related to that.
Sorry for this useless post.
