Re: [Gnuplot-info] how to add this file into gnuplot??

[Tammo H. <Pu...@Ta...>]

Since columns 1-5 contain the same data in each colums, their 
content is not really intersting to plot. If you want to plot colums 6-
10 use the following syntax:

plot 'gnu_apache2.file' using x:y

where you replace x with the respective column number you want 
to have ploted in the x-axis, and replace y with the respective 
column number you want to have ploted on the y-axis, for example 
to plot column 9 vs 6 use

plot 'gnu_apache2.file' using 6:9

I hope this helps, 

Tammo

I used your commands but get an error again:

gnuplot> plot 'gnu_apache2.file' using 2:9
		                                           ^
              no data point found in specified file

Its a little bit complicated to use gnuplot, or?
