Is there any way to change the position of x and y tick marks and labels to be left aligned or right aligned? For instance, in the above example, tick mark for median of weights is in the middle and exactly where it should be. But tick marks and labels for the first one are in the middle and I would like to have it at the edge where grid lines are. It would be beneficial to describe the data range.

Thanks

If you happen to have Image Processing Toolbox, you can use the Image Viewer App. It has an overview tool and an pixel region tool that gives you what you’re looking for.

This should give you an idea: (requires Image Processing Toolbox)

im = imread('cameraman.tif');
h = imshow(im);
hp = imscrollpanel(gcf,h);
imoverview(h)
impixelregion(h)

Just tried it out and i think it could be very helpfull when debugging image processing.
It would be great if it was zoomable and if cell values re-apear when zoomed in.

Greatings
