THStack with hbar option

[mkovac]

Hi,

trying to plot 3 stacked histograms using hbar option. The problem is black histogram boundary line which appears on two stacked histograms and not on the third one. I want to ged rid of this line but nothing I’ve tried helps. SetLineColor method doesn’t help neither, the boundary line simply stays black.

Any ideas? Thanks.

Can you post you macro ? I will try to modify it to make it work as you wish.

It is a part of larger compiled code, not a standalone macro so I can post a few lines connected with this problem. Thanks.

Ok that does not help … I will try to make a reproducer …

Here it is. I do not see any problem:

{
   THStack *hs = new THStack("hs","Stacked 1D histograms");

   TH1F *h1st = new TH1F("h1st","test hstack",10,-4,4);
   h1st->FillRandom("gaus",20000);
   h1st->SetFillColor(kRed);
   h1st->SetMarkerStyle(21);
   h1st->SetMarkerColor(kRed);
   hs->Add(h1st);

   TH1F *h2st = new TH1F("h2st","test hstack",10,-4,4);
   h2st->FillRandom("gaus",15000);
   h2st->SetFillColor(kBlue);
   h2st->SetMarkerStyle(21);
   h2st->SetMarkerColor(kBlue);
   hs->Add(h2st);

   TH1F *h3st = new TH1F("h3st","test hstack",10,-4,4);
   h3st->FillRandom("gaus",10000);
   h3st->SetFillColor(kGreen);
   h3st->SetMarkerStyle(21);
   h3st->SetMarkerColor(kGreen);
   hs->Add(h3st);

   hs->Draw("hbar");
}
