Plotting Rows in a File
Jasmin and Varqa Khadem
I was wondering how I can plot rows (within a
space delimited file) against each other.
As far as I understand with GNUplot one can
plot columns of data, e.g.
plot 'filename' u 1:3 not w lines.
Is there a syntax to specify the n-th vs.
m-th row of the same file?
yours sincerely,
Varqa Khadem

No. You'll have to transpose the file with an external tool before
presenting it to gnuplot.
The reason is that gnuplot wants to read the file sequentially,
datapoint for datapoint. With a file organized into rows instead of
columns, it can't do that.

No, there isn't. You'll have to use some external tool to transpose your
data.
