Hi Rooters,

I have been trying to draw the errors as a box but some how it doesn't draw the box. I am pasting my macro below,

Thanks for any help.

Regards
Monika

  c1->SetFillColor(kWhite);
  TMultiGraph *mg = new TMultiGraph();

  Int_t n = 3;

  Double_t xCERES[] = {8, 13, 18};

  Double_t exCERES[] = {0,0,0};
  Double_t eyCERES[] = {0.00005, 0.00005, 0.00005};

  gr1 = new TGraphErrors(n,xCERES,yCERES,exCERES,eyCERES);

  gr1->SetMarkerColor(9);
  gr1->SetMarkerStyle(20);
  gr1->SetMarkerSize(1.4);

  mg->Add(gr1);

  TBox *box = new TBox(13, -0.0004, 14, -0.00007);

  box->SetLineColor(kBlack);
  box->SetLineColor(kBlack);
  box->SetLineWidth(2);
  box->SetFillStyle(0);
  box->Draw();

  mg->Draw("A.P");
