Re: gStyle->SetErrorX(dx)

Hi,

so what's wrong with this code then:

{

gStyle->SetErrorX(0.0);

h1 = new TH1F("h1", "h1", 2, -0.5, 1.5); h2 = new TH1F("h2", "h2", 2, -0.5, 1.5);

h1->Fill(0);
h2->Fill(0);
h2->Fill(0);
h2->Fill(1);

h = new TGraphAsymmErrors(h1, h2);

h->Draw("AL");

}

Does draw x error bars.

Is there a way to disable those without using an additional array?

cu,
Alexander
