gnuplot - 如何用 Gnuplot 演示 LaTeX 公式？

Question

我试图用 Gnuplot 5.0 演示 LaTeX 公式。但是我发现有些 LaTeX 命令不可用。

这是我的 Gnuplot 代码:

set termoption enhanced

set title   "Title test^a \alpha $\alpha$" font "CMU-Serif, 18"
set xlabel  "Month"
set ylabel  "Precipitation (mm)"
set xrange  [0.5: 12.5]
set xtics   1,1,12
set key
set pointintervalbox 2

plot    "08_Data.dat"   using 1:2 with linespoints \
                        linecolor "#FF7800" linewidth 2 pointtype 7 pointsize 0.75 pointinterval -1 \
                        title "Beijing",\
        "08_Data.dat"   using 1:3 with linespoints \
                        linecolor "#00A0DC" linewidth 2 pointtype 7 pointsize 0.75 pointinterval -1 \
                        title "Shanghai",

set output
pause (-1)

因此，LaTeX 命令 test^a 运行良好，但 LaTeX \alpha 和 $\alpha$ 不起作用:

这是文件:08_Data.dat:

1       2.5     38.1
2       5.1     58.4
3       10.2    81.3    
4       25.4    101.6
5       27.9    114.3
6       71.1    152.4
7       175.3   129.5
8       182.9   132.1
9       48.3    154.9
10      17.8    61.0
11      5.1     50.8
12      2.5     35.6

   set term tikz standalone size 7cm, 3cm fontscale 0.6
   set ylabel '{\LaTeX\ -- $ \gamma $}'
   set xlabel '{\LaTeX\ -- $ x $}'
   set output 'example.tex'
   plot [0:1] gamma(x) title '$ \gamma(x) $'
   unset output
   !pdflatex example
