Hello,
I have a simple function generated by h2root from a ntuple. The
following histograms come out :
root [40] f.ls();
TFile** pbsil2.root
TFile* pbsil2.root
KEY: TTree h1;1 PSIL
KEY: TH1F h11;1 DESTEP
KEY: TH1F h12;1 STEP
KEY: TH1F h51;1 XSHOW
KEY: TH1F h13;1 STEP
KEY: TH1F h14;1 DEDX
KEY: TH1F h27;1 ESILI
but when I try to Draw them it occurs:
root [42] f.Draw('h11');
Error: Can't call TFile::Draw('h11') in current scope
FILE:/tmp/fileR0xGij_cint LINE:1
Possible candidates are...
filename line:size busy function type and name (in TFile)
(compiled) 0:0 0 public: virtual void Draw(Option_t* option);
filename line:size busy function type and name (in TDirectory)
(compiled) 0:0 0 public: virtual void Draw(Option_t* option);
filename line:size busy function type and name (in TNamed)
filename line:size busy function type and name (in TObject)
(compiled) 0:0 0 public: virtual void Draw(Option_t* option);
*** Interpreter error recovered ***
How should I proceed ?
Salutations,
Steve
