I have a long datafile (450 columns), which is like:
x y z x y z x y z...
1 2 4 2
4 3 5 5
7 4 6 8
10 5 7 11
Three columns are related and I would like to plot in one diagram 1 vs 2, 4 vs 5, 7 vs 8,...
And in a second diagram 1 vs 3, 4 vs 6, 7 vs 9,...
y and z are variables calculated dependent on x.
I tried, e.g.,
plot for [col=2:10:3] "file.txt" using 1:col with lines
This plots the y values but only vs the first column for x. Is there maybe a possibility to write in the using command to plot vs every nth column?
Thanks for help!
