This is the first time I’m using the TEllipse class and I’m really confused about one thing.
I want to draw a circle around a specific point of a 2D Histogram, let’s say (1,1). I’m setting the radius of the ellipse to be equal, but I’m still not getting a circle (I know this is a pretty dumb question, sorry)
This is the piece of my code where I try to draw the circle:
//ellipse with (1,1) center and r1 = 1 and r2 = 1 TEllipse *circle = new TEllipse(1.,1.,1.,1.); circle->SetFillStyle(0); circle->SetLineColor(kRed); circle->SetLineStyle(kDashed); circle->SetLineWidth(2); circle->Draw();
I want to create a circle with radius r=1 around the point (1,1), but this is what I get:
Once more: my apologies for the super simple question.
