- You'll need hold on to prevent wiping out the axes on each call.
- image sets the x and y limits the first time you call it, and doesn't set them again on future calls. You can set your limits manually to whatever values you want, or just use 'axis tight' (or 'axis padded') for convenience.

Hello everyone.
In my matlab code I have a graph like this one.
I implemented these lines of code so that I'm able to display a certain image in my graph in a specific position.
[img, ~, tr] = imread('ancora.png');
im = image('CData',img,'XData',[-0.3 0.5],'YData',[-0.3 0.5]);
im.AlphaData = tr;
However, I need to insert that specific figure multiple times in my graph in specific points, but I'm struggling to do so.
How can I insert that Image multiple times in my graph in the positions that I want?

You can call image multiple times, specifying your x and y separately with a few caveats:
im=imread('peppers.png');
image([1 20],[1 25],im)
hold on
image([40 60],[50 75],im)
image([10 30],[30 55],im)
axis tight
