Hi everyone, I’m trying to run the macro with the following command.
ch1->Draw(TString::Format("F3PLA_TR_ns - F3PLA_TL_ns: (1-%f)/TMath::Sqrt(F3PLA_QL)", slope1)>>hist1,"(PPACX>4.5 && PPACX<5.5)","colz"); hist1->Fit("fit","","",0.033,0.039);
now what I’m trying to do there is to plot a 2D histo of (A-B) : (1-f)/Q where A, B and Q are different branches of the tree. and f is a double obtained by fit2->GetParameter(1);
The error I’m getting is something like this:
/usr/include/c++/7/iomanip:418:5: note: candidate template ignored: could not match 'basic_istream<type-parameter-0-0, type-parameter-0-1>' against 'TString' operator>>(basic_istream<_CharT, _Traits>& __is, _Get_time<_CharT> __f)
Any suggestions on how to get rid of this or any other suggestions about plotting a 2D histo of (A-B) : (1-f)/Q?
