Dear ROOT users, I have a problem with graphs when I try to plot a point immediately after calculating its value - updating the graph during runtime. With TH1F this works - the plot is filled but with TGraph I don't see any updating. Here is a piece of code - I tried to compare in which way this is possible: //TGraph TCanvas *can = new TCanvas("Graph", "Graph!"); Float_t *a = new Float_t[100]; Float_t *b = new Float_t[100]; TGraph *gr = new TGraph(100, a, b); gr->Draw("AP*"); for (int i = 0; i < 100; i++){ a[i] = i; b[i] = 5 * sin(i); can->Modified(); can->Update(); printf ("calculated\n"); gSystem->ProcessEvents(); } //TH1F TCanvas *c1 = new TCanvas("c1","Time on axis"); Float_t bins = 1; TH1F *ht = new TH1F("Histo","Histo",100,0,10*bins); ht->GetXaxis()->SetRange(1, 1000); ht->GetYaxis()->SetNdivisions(1000); ht->SetMarkerStyle(20); ht->Draw("AP*"); for (Int_t i=0;i<100;i++) { Float_t val = sin(i); ht->SetBinContent(i,val); c1->Modified(); c1->Update(); gSystem->ProcessEvents(); } Do I miss anything? Do you know a way to achieve this? I'm using Linux Suse 8.2 with ROOT 3.10 Thanks
