Hi, I'm trying to use the TH1::GetHistogram() method to get a histogram fitted to a certain formula. Using the simplest case I could think of, I tried root [0] TF1* identity = new TF1("identity", "1", 0., 10.); root [1] TCanvas c_new; root [2] TH1F* idH = (TH1F*) identity->GetHistogram(); root [3] idH->Draw(); Error: illegal pointer to class object idH 0x0 136 FILE:/tmp/fileAGKUbL_cint LINE:1 *** Interpreter error recovered *** but got the error above. Any suggestions on what to do? Also, I noticed that if a TCanvas does not already exist, there is a segmentation violation. Does anyone have thoughts on how to work around this? Thanks, Raj Bhatnagar
