I have been learning more than I anticipated I would about gnuplot lately. I've been making up figures for a professor's paper (for which I've been doing research this summer) and now that we're down to the near end, there seem to be a fair bit of specifics involved. I've also picked up some useful abbreviations:

originalshort form
xrange, yrangexr, yr
l, p, lplines, points, linespoints

It's been especially useful to have found out how to make plots shell script style, a la:


set terminal postscript eps enhanced color
set output "something.eps"

set size square
set xr [-1:1]

plot exp(-x**2) ti "woo"
