[Gnuplot-info] How to Fit two data files in a same range in a sigle plot

[user_prady <pra...@ya...>]

Dear Experts,

          I m genuinely new to Gnuplot, so I need a help badly..Hope this
form is the best place.

 My problem is as follows:

Now I m plotting two data files in a sigle plot with the following simple
command.
Plot "I_indat.txt" with lines, "I_outplot" with lines 

Now problem is The file called I_outplot has 4 times data than I_indat.txt.
I want to plot the data of both the files in a sigle plot as it should take
one sample from I_indat.txt for 4 samples of I_outplot. I mean the graph
ratio should be 1:4 where I_indat.txt:I_outplot = 1:4
Here I ve attached the files.
Please help me with a code..

Thanks in Advance

either
   reproduce the data to have common x-values (e.g. seconds)
or
   use x2axis:

set xrange [0:10400]
set x2range [0:2600]
plot "I_indat.txt" ax x2y1 with lines, "I_outplot" with lines

That's not the real problem.  The real problem is that your data files 
have only a single column.  So gnuplot has to invent an x column for 
you.  But you can help it, by specifying a 'using' option:

	plot "I_indat.txt" using ($0/4):1 with lines, \
              "I_outplot" using 0:1 with lines

Or you could change your data file to actually contain the x data.
