I see ! still there is one thing left

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:


sorry , can it be merged ?

With the cleaned up mc.cpp macro I have. I get the following output using Aclic.

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.
