It sounds like what you are trying to do is determine the coordinates of a point on a graph. If so, try the following (with Mathematica running on a Mac):

Select the plot
Hold down the cmd key and move the cursor over the plot.

You will see the cursor change into cross hairs and the coordinates will appear at the bottom of the window on the left hand side.

There is a similar proceedure for Mathematica running under Windows, but I don't recall the key that needs to be held down. It should be either the cntrol, alt or Windows key.
