Data cursor in images

Hi, 

is any of the current graphics backends capable of a data cursor?

I.e, I click onto a plot generated by imagesc() and it gives me the
value of the matrix at that point?

I'm not picky, it doesn't need to be pretty or stable, and if it prints
the value to the prompt instead of showing it in the image, that's fine
as well.
