A collection of C++ macros, Python scripts and notebooks helping to learn ROOT by example.
You can execute the scripts in $ROOTSYS/tutorials
(or sub-directories) by setting your current directory in the script directory or from any user directory with write access.
Several tutorials create new files. If you have write access to the tutorials directory, the new files will be created in the tutorials directory, otherwise they will be created in the user directory.
You can start by executing the standard ROOT demos with a session like:
or
You can execute the standard ROOT graphics benchmark with
or
The $ROOTSYS/tutorials
