Changing ROOT version for comparison

ROOT
1

Hi,
recently I worked with ROOT 6.28 and get nice pictures. Today, I saw that the ROOT version is 6.32 and that gives me others pictures display. Is it possible to recompile my pictures with ROOT 6.28 in order to see what is different ?
I thinked to something like : python3 MyFile.py --ROOTVERSION=6.28
Is it possible ,

Thanks
Arnaud

Hello Arnaud,

What you propose might be possible. However, I think the usual way would be to set up two environments, for example in two different shells, and compare. E.g. :

. path/to/root/628/bin/thisroot.sh
python3 MyFile.py

and

. path/to/root/632/bin/thisroot.sh
python3 MyFile.py

Cheers,
Danilo

It look good. Now I have to find where are the different ROOT folders.
Many thanks
