I am trying to extract data from a pixel in an image that is plotted on an axis. I have tried both ginput and gpa, both of which do not work. I believe the problem is caused by the image being plotted with imagesc (it's a colormap, essentially) and that the image essentially covers the axis, so that it never received the input from the mouse click. I have not figured out a solution for this, does anyone have any suggestions or a confirmed solution? Thanks.
