Hi Jacek, The problem you are observing is related to the order of execution of 'cd','Update' and 'DrawClone'. A safe work-around of to add c1->Modified();c1->Update(); after each 'cd'. We will be adding a permanent fix soon. Cheers, Philippe. -----Original Message----- From: owner-roottalk@pcroot.cern.ch [mailto:owner-roottalk@pcroot.cern.ch]On Behalf Of Jacek M. Holeczek Sent: Monday, March 04, 2002 4:00 AM To: RootTalk Subject: RE: [ROOT] how to change the "title" of a pad > Sorrowfully I am not able to reproduce the problem. I tried with Try this ("root [0] .x blah.cxx"): ---------- void blah(void) { TPaveText *p = (TPaveText *)0; Float_t x[3] = {1,2,3}; Float_t y1[3] = {10,20,30}; Float_t y2[3] = {11,22,33}; TGraph *g1 = new TGraph(3, x, y1); TGraph *g2 = new TGraph(3, x, y2); TMultiGraph *mg = new TMultiGraph("MM","MyMulti Pad"); mg->Add(g1); mg->Add(g2); TCanvas *c1 = new TCanvas(); c1->Divide(1,2); c1_1->cd(); mg->DrawClone("A"); g1->Draw("L"); c1_1->Update(); //if ((p = ((TPaveText *)(gPad->FindObject("title")))) != 0) // { // p->Clear(); p->InsertLine(); p->InsertText("First Pad"); // } c1_1->Modified(); c1_2->cd(); mg->DrawClone("A"); g2->Draw("L"); c1_2->Update(); //if ((p = ((TPaveText *)(gPad->FindObject("title")))) != 0) // { // p->Clear(); p->InsertLine(); p->InsertText("Second Pad"); // } c1_2->Modified(); c1->Update(); return; } ---------- Then replace "DrawClone" with "Draw", to see the proper result. My ROOT is 3.02/07 on a RH6.2/i386 with egcs-1.1.2 Jacek.
