Hey Neil,

It is my understanding that you want to rescale(stretch) the 4th image such that only a selected portion (RGB part of the image) is displayed on the predefined axis.

A possible workaround could be:

Accessing the 4th location in the plot by using the subplot function. For your example you can use "subplot(1, 4, 4)" to access the 4th location.
Rescaling the image by changing the 'Xdata' and 'Ydata' property of the 'imshow' function.
Use the 'imcrop' function to crop out the required part of the image.
