dear sankeyo,

I have to say that I'm basing my responses on speculations, as your
question could have been less elusive...

that said, pgfplot(s) uses TeX to make a fine plot of your data when
the data is contained in an external file, or can be specified by an
analytical expression... imho if you NEED to use pgfplots you have two
choices

 1. if what you have is JUST a graph, you can digitize it to
    reconstruct the original data to be fed to pgfplots, please see
    http://en.wikipedia.org/wiki/Converting_scanned_graphs_to_data

 2. if you can run again your simulation, instead of plotting your
    results ask »Concept II« to save the results in a text file, to
    be fed into pgfplots as described in its fine manual

a further option is to use gnuplot, possibly from »Concept II«, to
produce an image format that you can include in your LaTeX document

if you want to follow the gnuplot way, here you will find many kind
and helpful people, if you want to stay with pgfplots you'd better ask
on the comp.text.tex newsgroups where, of course, you'll find other
helpful people as well
