How to rotate a LaTeX ylabel in gnuplot?

Question

I would like the ylabel on a gnuplot to be the same as $\omega_2(R_{3,n})$ appears in LaTeX. But if I use the following, it overlaps with the plot itself.

set ylabel "\omega_2(R_{3,n})"

One way to get around this problem is to rotate the ylabel by 90 degrees. How can that be done?

Answer 1

You could try the following (source):

gnuplot> set lmargin 20
gnuplot> set label 1 '\omega_2(R_{3,n})' at graph -0.2, graph 0.5

Somewhat unrelated here, but don't you need to use write $\omega_2(R_{3,n})$ when trying to produce LaTeX-output with gnuplot?
