Pass argument to fill histogram (from batch)


I am trying to fill histogram passing the argument via batch, like in the following manner:

for i, evt in enumerate(f):


where f is my file .root and variableX takes is “value” from outside:

variableX = args[’-x’] from -----> (python -x my_var)

The program works correctly, I mean without error but I found a problem when I want to plot the histogram: in fact the histogram is peaked at zero.

how I can avoid this problem?

Thanks you

I’m not sure to understand your question. Maybe @etejedor can help?


Can you share an example (e.g. an image) of what the issue with plotting the histogram is?

This does not look like a Python problem in any case?
