I'm not sure what you mean by "read."  You can get the Mathematica 3.0
front end to display the coordinates of the location of your mouse
pointer within a 2-D graph by doing the following: 

1) Click on the graph, so that its bounding box appears.

2) Move the mouse pointer within the graphic.

3) Hold down the Mod1 key (Unix).  The x-y coordinates will be displayed
in the status area at the bottom of  notebook window.

I think the equivalent keys for Windows and Macintosh are Ctrl and
Command respectively, but don't quote me on that :-).
