I was trying to plot multiple observables from multiple files using a for-loop over the files and THStack for the histograms to plot in the same canvas. But by doing that I am getting a blank canvas. But instead, if I use only one file (i.e., without the for loop over the files), then it is plotting fine with THStack. I have been trying different things but nothing is working. Could you please help me to find where I have made mistakes?
I have attached a small macro here. Let me know if I need to give the example datafiles.
Thanks a lot, @Wile_E_Coyote. This thing I tried, i.e., while using only one inputfile. Earlier also I followed the same procedure to plot variables from a Delphes output file using Delphes library. I corrected one mistake; the line TH1F *histM0[ii], *histM1[ii]; should be put outside the file loop. But still it is not working. So I have attached the corrected macro and two example datafiles.
