Dear Rooters,
what mistake do i make:
Running :
{
TCanvas *c1 = new TCanvas("data1","");
c1->SetLogx(1);
c1->Draw();
TH1F *h2 = new TH1F("","",1, 0.01, 1);
h2->SetMaximum(10);
Float_t x[4]= { 0.1, 0.2, 0.4, 0.5 };
Float_t y[3]= { 1.1, 1.2, 1.4 };
h2->Draw();
TH1F *h = new TH1F("","",3, x);
h->SetBinContent(1,y[0]);
h->SetBinContent(2,y[1]);
h->SetBinContent(3,y[2]);
h->Draw("same");
}
gives:
Error in <TGraph::PaintGraphHist>: X must have N+1 values with option N
but it has ... 3 bins -> 4 x-values
Ciao
Thomas
