I don't know if this is even possible, but if it is then someone on this list will know:
I have a jpg image with a "wobbly" line cartesian graph [ XY axes etc ].
Is it possible by importing it, to get mathematica to "read" the graph and produce a table of coordinates ?
Obviously the table could be scaled subsequently to produce desired results to match the original graph.
Sorry if this is a daft question
