I don't use windows, but I believe that this problem usually indicates
that gnuplot (i.e., the program, not the Python interface) didn't start
up correctly.  It could be a PATH problem, for example.  If you search
the mailing list archives you will see several similar questions and
responses.

[Including the above paragraph :-) ]

I just added this question to the FAQ.

Windows users are encouraged to submit a patch to produce a better error
message for this situation.  It would help new users a lot.  (Just
remember that it has to work for all windows versions.)
