is it possible to draw a square of width 1000 pixels, which is always 1000 pixels wide, even if the size of the window is changed on the screeen?

I am trying to create an array of dots, each one pixel wide/tall so that the colour of each pixel can be specified. thanks

I would use portions of this http://www.mathworks.com/matlabcentral/answers/100792-in-matlab-how-do-i-obtain-information-about-my-screen-resolution-and-screen-size. In this link they discuss how to get the number of pixels within the screen. Then using the get(__,'Position') or set() you can then derive how big your figure window is and then what that entails for the size of the axes you are plotting.

I'd make sure the 'units' property of everything is in pixels. Then I'd see if I can get into the callback of the gui resize event and put in a set(handles.axes1, 'Units', 'pixels', 'Position', [1,1,1000,1000]) or something like that.
