I want to do a fit to a function and then pluck the function from the TGraph object. I have the following macro, which shows that "func" doesn't point to anything. I managed to get a hold of the object through GetListOfFunctions, and found that the function does in fact think it's name is "pol2". So what's wrong with this code? { Float_t x[] = {1,2,3}; Float_t y[] = {1,4,9}; TGraph *tg=new TGraph(3,x,y); tg->Fit("pol2"); tg->Draw("AL*"); TF1 *func; func=tg->GetFunction("pol2"); cout << func << endl; } Thanks, Greg
