[Gnuplot-info] plotting multiple data from multiple files on one graph

[<kul...@gm...>]

Hi,

Using Gnuplot 4.6 I'm trying to plot multiple data from multiple files 
on one graph. Lets say in each file I have 3 columns and I want to plot 
2 and 3 against 1 (x axis), to compare each column (2:1 and 3:1) between 
files . I'm using 'plot for' construction:

plot for [i=1:10] sprintf("file_%d", i) u 1:2 w lines u 1:3 w lines


The problem is that the graph shows column 2 and 3 values just for the 
first file being processed, for the others only last column is 
presented. Is there a way I would be able to present all columns for all 
files?


best regards.
