Hi, I am wondering how I can change the font size of the text in a
legend (key). The default size looks small, but I searched the whole
entry of "set key" in the manual and got nowhere. Is there anyway I
can change it? Thanks!

Use enhanced text mode to set the title of the plot to whatever you like:

plot "foo" with lines title "{/Times=25 Big Title!}",
"baz" with dots title "{/Times=8 Little Dots}"

例如，这是我画能带结构的脚本：#
set term postscript enhanced color solid "Times-Roman,25"
set output 'band.eps'
set ylabel 'E-Ef( eV)' font "Time-Roman,25"
set size 0.6,0.8
# set format y "%.1f"
set border 31 lt -1 lw 2.000
set ytics nomirror set yrange [-1:1]
set xrange [0:0.155370]
set xzeroaxis
unset xtics
set ytics font "Time-Roman,25"
set label "{/Symbol G}" at 0,-1.10 font "Times-Roman,25"
set label "X" at 0.15,-1.10 font "Times-Roman,25"
plot 'Bands' u 1:2 w l lt 1 lw 4 title "{/Times=22 up}" ,'Bands' u 1:3 w l lt 3 lw 4 title "{/Times=22 down}"

画透射谱：
set term postscript enhanced color solid "Times-Roman,25"
set output '000000.eps'
set size 1.0,0.8
set border 31 lt -1 lw 2.000
set ytics font "Time-Roman,25"
set ytics 0.4 font "Time-Roman,25"
set xtics 0.2 font "Time-Roman,25"
set xzeroaxis lt 0 lw 3
set yzeroaxis lt 0 lw 3
set xrange [-1:1]
set xlabel 'E (eV)' font "Times-Roman,25"
set ylabel 'T(E)' font "Times-Roman,25"
plot 'trans.out' u 1:2 w l lt 1 lw 5 title "{/Times=18 transmission}"

在plot 语句前加上set size 0.5,0.5可以使得自己话的图变粗变好看！
