Hi, I would really appreciate if somebody could tell me what I am doing wrong. I need to generate a lot of plots at short intervals. So I do a graph in a canvas and use the Print() method to print a postscript file . But I noticed that the Print() method causes an increasing amount of memory to be used. How can I prevent this and free the memory? Below is a sample code where this can be observed (do top from a shell and watch...) Any help would be appreciated. I use root 3.00 /egcs 2.91.66 Thanks, Tome void testMemory() { Float_t X[100]; Float_t Y[100]; TCanvas *c1; c1 = new TCanvas("c1","canvas"); for (Int_t i=0; i< 100;i++) { X[i] = i; Y[i] = i; } TGraph* grh = new TGraph(100,X,Y); grh->Draw("AL"); while (1) { cout << " do plot " << endl; c1->Update(); // this causes memory to be used and NOT freed c1->Print("xxx.eps"); } }
