Maybe use Google? http://www.cs.hmc.edu/~vrable/gnuplot/using-gnuplot.html
http://lowrank.net/gnuplot/index-e.html is also a good source I use to refer to get help with gnuplot. Hope that will help. [snip]
Actually, I'm not sure that will help her do what she wants to do. Traditionally, gnuplot data files contain multiple columns, e.g.:
# x y 1 2 5 10 6 12
rather than two single-column files, and I think the latter is what she wants. I don't think that gnuplot supports that (though I could be wrong). Thus, I think she needs to merge her two files, e.g.
plot "< join file1.dat file2.dat"
if I remember right....
As an aside, if you are going to be doing any data manipulation or regression or such, I'd consider moving to R. I have a lot of respect for gnuplot, and I used it a lot as a grad student, but just about everything I want to do I can do in R and make it look better. The learning curve is a bit nontrivial, but I've found it worth it.
