[Gnuplot-info] plotting out of two datafiles at once?

[Thomas P. <jun...@gm...>]

Hi,
I am wandering how I would plt a simple x-y plot where I have the x data in one column 
of file1.txt and the y data in file2.txt. I.e. the x-data do not change and I have 100s of 
different y-datafiles. To save memory, I only saved the x-data once. I am using Gnuplot 
4.0.  I did already look into help plot -> datafile -> sepcial but could not find a solution.
I know I could write a simple c-program to read-in data, save the 2 columns of interest 
in a dummy file and plot this one, however, I was wandering if there is a simpler way. 
(Perhaps with sed or awk in the plot file?). I am not familiar with these linux commands 
Thanks a lot for your help
Cheers
Thomas

Zipping the data would have worked better...

Of course there is.  Somebody already wrote that program for you.  It's 
called 'paste', and should be available in a friendly Unix toolbox near you:

	plot "< paste xfile.dat yfile_5.dat"
