Digitize linear and (semi-)log scale graphs with multiple point sets

Working on a paper, I ran into the problem of needing data from a graph that was not mine, and for which no underlying table was published. With today's software packages, it is however not very difficult to digitize a figure yourself. I remembered rea...
