Hello I would like to pass in a function a vector of pointer of the class TH1d *, here is what my code look like in the main() function :
(. . . )
vector<TH1D*> SA_pTl_MCtru_histos ;
for(int i=0 ; i<=nb_of_sa ; i++)
{
// a. Construct string for current mass sample
string mW = "m0" + GetStringFromInt(i) + "_" ;
// b. Get coresponding histogram
TH1D * current_SA_histo = GetHisto(SA_root_files[i], PD_HISTO_P+mW+obs) ;
SA_pTl_MCtru_histos.push_back( current_SA_histo ) ;
}
(. . . )
TCanvas * can_lla_MC_truth = Make_lla(PD_pTl_MCtru_histo,
SA_pTl_MCtru_histos,
options) ;
(. . . )
And here is how I declared the function that is being called :
TCanvas * Make_lla (TH1D * data, vector<TH1D*> samples,
string * options)
After some debugging it appears that my vector of TH1D * is not passed very well, can someone give me a tip here ?
Thanks in advance
