How do I switch x and y axes?

My code reads raw data from a file (that ends with .raw) and assigns arrays from the raw data such as data = raw (1:512, 1:128) but when I display this data with the statement as follows: imshow(data, 'Parent', handles.ax), the x-axis and y-axis data were displayed in reverse. How can I switch those x-axis and y-axis data? It s probably very simple but can't seem to find a good example in this newsgroup!

I'm not sure what your exact issue is.
The right combination of functions "view", flipud, fliplr, and transpose: data' should be able to handle whichever flipping you'd like.

I don't want to rotate or move the image around since when I attempt to zoom it, it won't work if it is rotated around. Just switch x and y axis data.

Then simply transpose the data before plotting it?
data = raw(1:512,1:128);
data = data' ;
