TGraphAsymmErrors

ROOT
1

Dear all,

Is there any way to remove horisontal ticks at the ends of the vertical error bars for
TGraphAsymmErrors::Draw(TString option="")

what the “option” should be ?

the manual refers to :
TGraph::PaintGraph
which does not say if there is any way to do what I want.

thanks
Igor

my code and pdf are attached


#include "TGraphAsymmErrors.h"

TGraphAsymmErrors *graph;

void test_tgrapherrors()
{

    graph=new TGraphAsymmErrors(1);
    graph->SetPoint(0, 1., 1.);
    graph->SetPointError(0, 0., 0., 0.1, 0.2);

    TH1D* plot=new TH1D("plot","plot",10,0.,2.);
    plot->SetMinimum(0.);
    plot->SetMaximum(2.);
    plot->Draw();

    graph->SetMarkerStyle(20);
    graph->SetMarkerColor(99);
    graph->SetLineColor(99);
    graph->Draw("E0pSAME");
}
