Hello, Is it correct that histogram like attributes of a graph must be handled by the GetHistogram() function ? The program below runs under WINNT, visual C++ 6.0, root 2.24/05, but crashes if I include the line that is commented out. #include <TRoot.h> #include <TCanvas.h> #include <TPad.h> #include <TApplication.h> #include <TGraph.h> #include <TH1.h> extern void InitGui(); VoidFuncPtr_t initfuncs[] = {InitGui, 0}; TROOT root("rint","The ROOT Interactive Interface", initfuncs); int main() { TApplication* pRootApp = new TApplication("RootApp",0,0); TCanvas* c = new TCanvas("c1","bla",200,10,600,400); TPad *pad1 = new TPad("pad1","The pad",0.05,0.52,0.95,0.97); c->SetGrid(); float x[3]; float y[3]; x[0] = 0.0; y[0] = 0.0; x[1] = 0.5; y[1] = 0.5; x[2] = 0.9; y[2] = 0.9; TGraph graph(3,x,y); graph.SetTitle("linear"); // graph.GetHistogram()->SetLabelSize(1e-1); graph.Draw(); c->Modified(); c->Update(); while(1) ; return 0; }
