I have a histogram like this:
TH1F* h = new TH1F("asd","asd",100,0,1000);
how can I change the scale on the x axis?
I want to do something like this…
h->ChangeXScale(1000);
and now h should be the same as
TH1F* h = new TH1F("asd","asd",100,0,1);
For example: Lets say the original histogram has on the xaxis energies from 0…1000keV, how can I change the histogram to have on the xaxis 0…1MeV (with same number of bins, actually not changing the underlying data at all)
