Hi all,
I draw a rectangular in a figure by the code,
roi = drawrectangle('color','r','linewidth',2);
And now I want to set the rectangular invisible, so I code like this:
H = findobj(handles, 'type','rectangle');
set(H,'visible','off');
But this code does not work at all.
Could anyone help me to figure it out?
Thanks so much.

The following works for me:
roi.Visible = 'off';

similarly, you can use the object (already assigned to roi) with the set function as follows:
set(roi,'Visible','off')

Try this:
H = findobj('Type', 'images.roi.rectangle');
