i am using the drawcircle function in my program, i notice that the circle looks more oval
roi = drawcircle('Center', [3 3], 'Radius', 3); %code used in the program
the output i received looks more of an oval than a circle
is it due to the stretching caused by a rectangular screen?
the output

Use:
axis('equal')
and it magically becomes a circle!
See the documentation on axis for details.
