Such a function would be really useful, at least to me.
I think that extracting the data would be a really impressive feat, though.
The function should recognize the axes, the axis labels, and the data points. In your example that might be sort of easy, e.g. because of the different colors. But I think it would get really messy for more complex (or plainer) figures I find in scientific articles.
Not impossible. But if someone accomplished that and he/she is willing to share it, I think I'm going to kiss my own elbows.
Anyway, asking does not cost a thing.
Maybe for some image processing wizard this is a piece of cake.
