savefig eps error

today i produced an image that failed to save to eps.
i can save the file in pdf, but i get the same error if i try to use
pdf2ps. png works too, but its not vector.

not sure if its important, but the image has 401 lines, with 500 points
each.

the image is produced from a bunch of data files and im not sure how to
most effectively send this over email ( in case you all wanted to
re-produced the error).

the main error is

Error: /nocurrentpoint in --lineto--

here is the whole error

thanks
alex
