I need to make a histogram with empty spaces between some bins, but continuous 2D bin numbering (ignoring the spaces). Probably TH2Poly with alphanumeric bin names is the best option (although I’ll have to subclass the TH2Poly so Fill(int1, int2, val) with call Fill(string(int1), string(int2), val)). I started simple and already have a problem. My bin labels do not seem to go where they should, below the bins. I would be grateful for a hint on what I am doing wrong:
OK, So I understand that when filling with a class that has IsInside() and inherits from TNamed, the poly-bin name becomes the name of the object with thick the TH2Poly was filled. But that, and the example with Europe refers to one string in Fill(). How to give a bin a name with 2 strings, as in the Fill() I referred to?
