Use the datacursor tool . You can activate that from the figure toolbar, or you can activate it inside a program by using datacursormode()

If you have the Image Processing Toolbox, use impixelinfo(). See the help for an example.
% Let them mouse around and see the values.
hPixelInfo = impixelinfo();
set(hPixelInfo, 'Unit', 'Normalized', 'Position', [.81 .89 .2 .1]);
Use the Position property to place the status label anywhere you want. I haven't tested it while ginput() is being called but it works all other times so I imagine it would still work then.
