Is there any way to create an array of the names of the histograms of a root file from inputting the root file? I saw that there is a way to create it using TList, however, I already ran the code which took 3 days, and I do not want to rerun it again by revising the code with TList.
I am trying to create a way to save all graphs as PNG files by inputting a root file. My root file has around 100 histograms. I created a function to convert the histogram to a PNG file, however, I need to input the names of the histograms. Also, I have an older version of ROOT (5.34/10) so the rootprint command does not work for me.
Thank you very much and I really appreciate any help,
