Re: Re: Names of histograms reset after TFileMerger

Dear Rene,
  Thanks for your answer.
  Indeed the histograms are merged correctly. But all the names of histograms are changed after merging also. after merging, it changed histosscaled 1, 2, ..., which I can not easily find the plot I want when I go futher.   I am trying to ask for your help how can I keep my defined names on each histogram after merging. Thanks a lot!
  Regards,
Yaxian
