Hi, You do not give enough info (example). Here is an example with a dynamic array of functions Rene Brun void af() { const Int_t nfunc = 10; TF1 **functions = new TF1*[nfunc]; for (Int_t i=0;i<nfunc;i++) { char fname[20]; sprintf(fname,"f%d",i); functions[i] = new TF1(fname,"gaus",-10,10); functions[i]->SetParameters(1,0,0.5+i/2.); if (i == 0) functions[i]->Draw(); else functions[i]->Draw("lsame"); } } On Thu, 16 May 2002 kmakonyi@nist.gov wrote: > Hi rooters, > > I'm a really beginner in the Root.
