plotting every nth row

[alpha beaver lo]

Instead of plotting every row of my data,
is there a way of plotting only every nth row?

Hm. Pipe it through awk, perhaps? Should work on unix and OS/2, at least.
Otherwise you may have to generate separate files. I don't know if 3.6 (beta)
can do it by now, but 3.5 AFAIK can't. Stefan

What version/command are you using?

In 3.5, 'splot' can do it (at least the question can be interpreted
so that the answer is 'yes') but 'plot' can't.

In 3.6, yes. for both 'plot' and 'splot'.

FYI, 3.6 beta has a plot 'file' every a[:b[:c[:d]]]

which plots every a'th point in every b'th line, starting at point c
in line d.

3.6 available from cmpc1.phys.soton.ac.uk for beta testing

I love it, David! 3.6 seems to grow whenever I turn around to get some
sleep .. :-) (Oh -- is there a doc in gnu-info or inof-tex form planned
on gnu-plot?) Stefan
