If you are picky about typography, then maybe you should use LaTeX. Gnuplot has a variety of LaTeX terminal types, such as tikz
, epslatex
, and cairolatex
. The downside is that you must then pass the generated plot through latex
or pdflatex
in order to render it, so plotting is not interactive. Also, you must learn some basic LaTeX.
There is a nice tutorial on using the TikZ terminal. That page gives the following example gnuplot script (xlabel
added by me):
set term tikz standalone color solid size 5in,3in
set output 'sin.tex'
set xlabel '$t_{\alpha\beta}$'
set xrange [0:2*pi]
plot sin(x) with lines
exit
Note that the exit
is important, otherwise sin.tex
will be incomplete. To turn this into a PDF, run pdflatex sin.tex
.
You still cannot control the positioning of the subscript (well, probably LaTeX will let you do this if you are expert enough), however the defaults were chosen by typographic experts who probably have a better eye than you or me.
