Gnuplot epslatex 中的字体大小

Question

I would like to increase the size of the fonts in the x and y axis, as well as in the key. I do not wish to change the size of the image. Using epslatex in gnuplot, can anyone suggest how to change the font size?

set terminal epslatex color size 7.0in,7.00in standalone
set out 'profile2.tex'
set xrange [400:600]
set yrange [150:280]
set size ratio 1.25
f(x)= -0.02*(x-500)**2+250
g(x)= -0.025*(x-500)**2+250
set xlabel "$x$"
set ylabel "$y$"
set key at 580,265 
plot f(x) w l lw 2.0 title "Initial condition"#, g(x) w l lw 3.0 dt 4 title "$\\alpha=0.025$"
set out
system('latex profile2.tex && dvips profile2.dvi && ps2pdf profile2.ps')
system('mv profile2.ps profile_TEST.eps')
unset terminal
set out

I have tried using

set terminal epslatex color size 7.0in,7.00in font '20' standalone

but the font remains unchanged

Answer 1

The syntax font ",20" works.
