The following programs allow you recover data values from a graph.
Data Thief allows users to reverse engineer a data set from a scanned graph in MacPaint or PICT format. It will automatically trace graphs, accepts either log or linear scale, and will calculate error from error bars if they are present. It enables users to retrieve data for which they have only the graph.
For more information, see http://www.nikhef.nl/user/keeshu/datathief/index.html. The manual is at this site.
