I use PlotDigitizer whenever I need such a tool and find it to be really good.
The point and click axis alignment and plot selection is easy to use and on
plots with lots of data, the "autotrace" facility works nicely (you just draw
a broad line over where the data is approximately found and the autotrace
library does the rest).
I talked to the upstream of PlotDigitizer some time ago about integrating it
better on linux machines (I vaguely recall that the upstream developer is a
MacOS X user). He was very responsive in dealing with problems that I found
and liked the idea of being packaged and used more widely.
The last time I looked at it, however, it had all the usual problems of the
java ecosystem (e.g. internal copies of libraries in the source download) and
the prospect of packaging that was a little daunting. There were also
problems with libraries that had been relicenced from GPL to GPL-incompatible
and PlotDigitizer upstream wasn't sure what to do about that. Given that
there have been no releases in 3 years, I think that probably tells us what
Packaging PlotDigitizer has stayed on my todo list, however, and I may yet
have a look at it. That said, there may be less fraught alternatives already
in the archive.
