Hi, I have a TH3F histogram and I cannot draw it with the glcolz option. I have attached the script and the root file, as well as the image produced. Using a transfer function for making empty bins transparent does not help. I would be very grateful for any suggestions on how to draw this histogram.
Thank you,
Cristian

Your historgam puts ROOT is a strange state. When I draw it with the option BOX only (no opengl) the view is blocked. I cannot rotate it. I see also some red line (coming from the list of functions I guess)
It was produced with a script analysing a huge ASCII file, and which has drawn the histogram following the use of the transfer_function which made the empty bins transparent. Then I wrote the 3D histogram to a another root file, so I can open it directly, without reading the huge ASCII file again. But it had already used the transfer function method which I got from post https://root-forum.cern.ch/t/th3-and-glcolz-option/14604
