Width of arrows in TH2::Draw("arr") option

ROOT

Is there any way to control the line width of the arrows drawn when using h2->Draw(“arr”)? Using h2->SetLineWidth(2) does not have any effect in v5.34 (Windows). Thanks.

Actually the method painting the arrow plot starts with:

   fH->SetLineStyle(1);
   fH->SetLineWidth(1);

So the line width and line style are hard coded to 1. May be only the line style should be ?

I would just remove those two lines from the code, so that it just gets the originally set line style and width.

Done.
