It would really help to see a representative sample of the data that you
are working with and what you want the plot to look like.  Other then that,
you likely just want to load the data from the file into lists (ordered
together, lists with sublists, or potentially into a list ofrepresentative
objects).  You can then simply open a pipe to gnuplot and send it the
commands it needs to create your plot.  You could also just create a single
comined file with all of the information to plot and then use it to create
you plots.
