It did work :-)
When you include other fontfiles you can use them for the whole plot.
Another, probably better, way is to use the epslatex terminal. Then you
can typeset everything with LaTeX-like strings (this is probably what
you were looking for).
To give you some examples:
set terminal epslatex standalone
set output "ex-file.tex"
set xlabel "$x$"
set ylabel "$\\sin(x)$"
set xrange[-pi:pi]
set xtics ("$-\\pi$" -pi, "0" 0, "$\\pi$" pi)
plot sin(x) t ''
Then you must run
gnuplot ex-file.gp && latex ex-file.gp && dvips ex-file.dvi
Then, every string is typeset using the roman Computer-Modern fonts. But
with the 'header' option you can add any package and command you want.
In my opinion, all labels should still be typeset in a 'sans-serif' font
which you can get as follows
set terminal epslatex standalone header \
"\\usepackage[T1]{fontenc}\n\\usepackage{cmbright}\\renewcommand{\\familydefault}{\\sfdefault}"
set output "plotsin.tex"
set xlabel "$x$"
set ylabel "$\\sin(x)$"
set xrange[-pi:pi]
set xtics ("$-\\pi$" -pi, "0" 0, "$\\pi$" pi)
plot sin(x) t ''
The cmbright package is needed, because the CM-Super fonts do not have a
sans-serif math font (if you omit this part in the header string, all
numbers will be sans-serif, but the 'pi' in the labels and the x- and
y-labels will be roman)
Hope that helps you :-)
