imshow moves figure to other monitor

David Doria — Wed, 14 May 2008 21:11:01 -0400

I have a dual monitor setup. If i do this

figure

then move the figure to the other monitor, then do

imshow(Data)

it moves the figure back to the original monitor

is there any way to prevent this? Is there a way to specify
which monitor figures get created on initially?

Thanks!

Dave

Hi David,

Try to use the Position property of the figure command, so
for example, if i wanted to make a figure that was one
quarter the size of the screen, positioned in the top left
corner, the following would do the trick,

scrsz = get(0,'ScreenSize');
figure('Position',[1 scrsz(4)/2 scrsz(3)/2 scrsz(4)/2])

Cheers,
Erik

yea i've used position in the past... but that still doesn't
say WHICH monitor to position it on? or does it treat them
both as 1 long one?

I'm assuming it would treat it as one long monitor. In fact,
when I change the parameters so the window opens outside of
my viewable area, I can see that it gets sent outside my
screen. I'm pretty sure this should work.

I have a similar problem to that posted below: I create a figure and use the 'Position' property to place it on my second monitor. If I display an image in this figure using 'imshow,' it moves the figure to the first monitor. I can then move the figure back to the second monitor using the Position property again, but I'd like to avoid this since it involves jerky flickering of the image position that makes it unusable for my application.

It looks like 'imshow' gets confused by the figure position being outside the bounds of the primary monitor (as reported e.g. by scrsz = get(0,'ScreenSize'); ). Any thoughts on how to get it to behave more intelligently would be greatly appreciated!

best wishes,

Raghu

An old thread, but for the benefit of the next person to search for this (like I did):
If you specify the parent, it seems imshow won't move the figure.
E.g.
imshow(im, 'parent', gca);
