There is a nifty little shareware program called TechDig, which lets
you pull out numerical data points from a scanned image.  You click
with the mouse on the ends of the axes, to establish the scale, and
then click on each data point and the X and Y values get written
to a text file.

You can download TechDig from ZDNet's software library:
http://www.zdnet.com/swlib/ (type TechDig in the search box)
It runs on Windows only.

Hope this helps,
