find exact coordinates of points from graph

Hello,

I would like to ask whether there is a program (matlab maybe?) where someone can take a graph from a scientific paper and be able to find the coordinates of the points of that graph.

The simple way would be for someone to use a ruler and pencil and find the points. Is it possible to be done from a program? And if yes, how this could be achieved?

Regards!

Try g3data - it's in the repos.

Works pretty well I think.

Hello,

I tested it with a graph I wanted to check and it is working like a charm!

Thank you, Regards!

Nice one xadder, thanks!
