Hi everyone,
I have a set of .root files of the form
xyz_1.root
xyz_2.root
…
xyz_2362.root (various numbers are missing in between the files)
Each file has a stored 1D histogram containing energy spectra.
I am trying to merge these 1D histograms into a single 2D histogram such that the X-axis is the unique file number and the Y-axis has the corresponding energies of that file.
Is there any built-in command (n similar lines of hadd
) that can help me achieve this? Any suggestions/examples in this regard will be helpful and appreciated.
Thanks a lot !
