从我的计算工具中，我得到了两个图，一个是 xmgrace，另一个是一些 dat 文件格式。xmgrace 格式的前几行（比如文件grace.agr）有刻度标签及其位置，我想在我的gnuplot 脚本中使用它们。我的grace.dat 看起来像（总的ticklabels 可能在这里我只提到几个）
@ page size 595, 842
@ view 0.120000, 0.150000, 0.900000, 1.280000

@ xaxis label char size 1.5
@ xaxis ticklabel char size 1.25

@ xaxis tick major 7, 3.83352
@ xaxis ticklabel 7 ,"A "
@ with g0
在代码部分中提到的 grep、awk 和其他一些技巧的帮助下，我设法将以下数据附加到文件中（比如文件名是 SETTICKS.dat）
cat SETTICKS.dat 给了我这个：
set xtics ( "\xG" 0.00000, "M" 0.67643, "K" 1.06696, "\xG" 1.84803, "A" 1.98549, "L" 2.66192, "H" 3.05245, "A " 3.83352, )
grep 'bandindex: 1' -B10000 grace.agr | grep xaxis | grep 'type both' -A 1000 | grep 'xaxis tick spec ' -A1000 | grep '0, 0.00000' -A1000 | awk '{print $5}' | grep -v '^[0-9]' | awk '{p
rint substr($1,2); }'| awk -F\| '{ print substr($1,1,4)}' > xlable-1.txt

paste x-tick-1.txt xlable-7.txt x-tick-2.txt > SETTICKS.dat
我想在 gnuscript 的两个位置使用上述grace.agr 文件中的刻度及其位置，如下所示
(1)
set xtics ("\xG" 0.00000, "M" 0.67643, "K" 1.06696, "\xG" 1.84803 ,"A" 1.98549, "L" 2.66192, "H" 3.05245 ,"A" 3.83352,) and then
(2)
set arrow from 0.00000,Y11 to 0.00000,Y12 nohead
set arrow from 0.67643,Y11 to 0.67643,Y12 nohead
set arrow from 1.06696,Y11 to 1.06696,Y12 nohead
set arrow from 1.84803,Y11 to 1.84803,Y12 nohead
set arrow from 1.98549,Y11 to 1.98549,Y12 nohead
set arrow from 2.66192,Y11 to 2.66192,Y12 nohead
set arrow from 3.05245,Y11 to 3.05245,Y12 nohead
set arrow from 3.83352,Y11 to 3.83352,Y12 nohead
其中 Y11 和 Y12 分别为 -10 和 10。
