The issue with using the rotate command on images is that the Image objects do not have ZData.
Normally, when working with something like a patch or surface, the rotate command collects the XData, YData, and ZData from the object, applies the requested transformation to the data, then updates the XData, YData, and ZData on the patch or surface.
This doesn’t work with images because Image objects don’t have ZData. Instead, when querying the data from Image objects, the rotate command assumes that the ZData is all zeros. It then applies the requested transformation, but because there is no ZData property on Image objects, it can only update the XData and YData properties, and the image remains in the x-y plane.
If you want to rotate images, you should use the hgtranform and makehgtform commands instead. For example, the following code will rotate both the line and image 45 degrees around the x-axis.
x = 100:100:1000;
y = randi(10,1,10)*50;
figure;
ax = axes;
ht = hgtransform(ax);
h = plot(ht, x,y);
im = imread('football.jpg');
i = image(ht, im);
ht.Matrix = makehgtform('xrotate', pi/4)
