Ctr-C does not make effect on this. Please give some help Sincerely yours Xie *********** button.C * *********** { gROOT->Reset(); bar = new TControlBar("vertical", "Demos"); bar->AddButton("activate oo.C",".x oo.C", "test for oo.C"); bar->AddButton("Close", "delete bar", "Delete control bar"); bar->Show(); gROOT->SaveContext(); } ******* oo.C * ******* { gROOT->Reset(); test = new TCanvas("test","",0,0,700,500); pad1 = new TPad("p1","",0.0, 0.0, 0.48, 0.9, 21); pad2 = new TPad("p2","",0.52, 0.0, 1.0, 0.9, 21); pad1->GetFrame()->SetFillColor(42); pad2->GetFrame()->SetFillColor(42); pad1->SetGrid(); pad2->SetGrid(); pad1->Draw(); pad2->Draw(); hist1 = new TH1F("h1","1st test hist",100, -4,4); hist2 = new TH1F("h2","2nd test hist",100, -4,4); ntuple = new TNtuple("ntuple","","x1:x2"); hist1->SetMarkerSize(0.7); hist1->SetMarkerStyle(20); ntuple->SetMarkerStyle(21); hist2->SetFillColor(48); gRandom->SetSeed(); float x1,x2; for(int i=0;i<100000;i++) { x1 = gRandom->Gaus(-1,1.5); x2 = gRandom->Gaus(-0.5,0.5); hist1->Fill(x1); hist2->Fill(x2); ntuple->Fill(x1,x2); if(!i%500) { pad1->cd(); hist1->Draw("elp"); hist2->Draw("same"); pad2->cd(); ntuple->Draw("x1:x2","x2>=0"); test->Modified(); test->Update(); } } test->Update(); }
