Hi,
I have tried both :
root.cern.ch/root/roottalk/roottalk00/2318.html
[TH2F histogram rebinning with different bin sizes
support to plot a 2D histograms with the variable bin width.
However, it doesn’t seem to work on ROOT version 5.26 nor 5.34.
p.s (in the 2nd link there is a typo in the answer code, where ; should be used instead of , in the loop)
Many thanks
Sarah
