This is probably a trivial question:
I have histograms with numbers as titles, and I try to plot them on the command line, but they are seen as numbers and I get this error:
root  _file0->ls() TFile** xbin_64-ybin_83-lines_5.root Line shapes for one bin TFile* xbin_64-ybin_83-lines_5.root Line shapes for one bin KEY: TH1F 120404;1 1.776669 KEY: TH1F 120720;1 1.776669 KEY: TH1F 121645;1 1.776669 KEY: TH1F 126836;1 1.776669 KEY: TH1F 128895;1 1.776669 root  120404->Draw() **ROOT_prompt_3:1:9:** **error:** **member reference type 'int' is not a pointer** 120404->Draw() **~~~~~~ ^**
I have for now just renamed the histograms, adding an “h” in the front, which works fine, but for various reasons its quite practical to have the number-only names - can I tell root on the command line that this is not a number but a histogram?
