Hello, what's the best way to create in matlab GUI (GUIDE) a "entrance effect". I mean, like you have in power point animation.
I have a certain image, let's say size = [1000 1000]. I'd like to show first (:,1:100) then (:,101:200) and so forth.
If I simply try to imagesc a certain slice of my image, it gets "smeared" all over the axes. How can draw each column of the matrix image at it's right location?
Also, what's the best way create a "smooth entrance left-to-right" effect? I was thinking on working with pause...is there a better approach? You know, something like the entrance speed you have in Power Point...

You can pass x and y coordinates of the corners to imagesc(). Please read the documentation about what the coordinates represent as you will probably want to add 1/2 to the "natural" coordinates to use.

I've found the solution. Simply needed to invert the order. First image... then set(ax, ....)
It draw slice perfectly.
THANK YOU.

I keep forgetting that the axes limits are cleared for new drawing if hold is not on.
