[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
