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;
}
