rectangle invisible in matlab

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';

[Turlough Hughes]

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

set(roi,'Visible','off')
