This is off topic for this list but:
it is not possible. You have first to merge file1 and file2 like this:
paste file1 file2 > merged
then you can plot what you want in gnuplot:
plot "merged" 1:2

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.

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.

How to make of use of GNUPLOT in Linux for plotting graphs by taking inputs from files?

2014-02-06 Thread Norah Jones
Hi, 

How to make of use of GNUPLOT in Linux for plotting graphs by taking input from 
files? Data in one file represents X-axis and other file data represents 
Y-axis. Can anyone help me out?

Thanks,
Norah Jones
