Hi,
    I am trying to fit histogram using defined fit function. It works well
when i am giving histogram name in the function. Now i want to do same
thing with different histograms  using variable name, i tried but it
is not working.

    I am having a main macro(say test.C) in which i define histogram and
filling, and i am having fit macro(say fitf.C) in which i define my fit
and doing fitting by calling  myfit();   (see attached files)

    In myfit() if i am giving histogram name(say Dca_phi_1) then
Dca_phi_1->Fit("fitf");  wroks fine. Now i want, instead of using
particular histogram name(Dca_phi_1), it take a variable histogram(say
hitsname), where histname is given in main macro(test.C)

Thanks for any help
 Avdhesh
