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 ?
