looked deeper into this. Turned out this was caused has my last dive has only a single temperature reading leading to an temperature plot of height zero which caused some geometry calculation to divide by zero. Here is a fix.

I hope that isnan() is available everywhere (the web wasn’t really sure about it). Of course the real issue is size==0.0 but how do I reliably test a float for zeroness, i.e. that I get NaN when I divide by it?
