It might be something local, but here is what happens. The graphs have the same shape in ACliC and interpreted, but really not the same scale ! And the histo show up with no bar when compiled. Here is what I get , in the two mode .
the last histo, compiled.
this was intended to be in the thread:
root.cern.ch/phpBB2/viewtopic.php?t=3600
sorry , can it be merged ?
I’ve re-installed my ROOT.
I was using my own installed version instead of the one shared on our network.
Now, if I compile with this version ( 5.10/00), instead of my own installed version (v5.11.06).
Anyway, thank you a lot for your support.
