从我的Calculationa工具中，我得到了两个图，一个是xmgrace，另一个是某种dat文件格式。 xmgrace格式的前几行（例如，它是一个文件grace.agr）具有刻度标签和它们要在gnuplot脚本中使用的位置。 我的grace.dat看起来像（总的ticklabels可能更多，这里我只提到了几个）
@ page size 595, 842
@ view 0.120000, 0.150000, 0.900000, 1.280000

借助grep，awk和代码部分中提到的其他技巧，我设法将以下数据附加到文件中（例如文件名为SETTICKS.dat）
cat SETTICKS.dat给了我这个：
设置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

我想在下面的gnuscript中的两个位置使用上面提到的grace.agr文件中的刻度线和它们的位置
(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分别是-10和10。
答案 0 :(得分：0)
我为您提供了一个仅使用awk的解决方案。
对于第一部分：
awk 'BEGIN {mystring="";FS=", *"}/tick major +[0-9]+/{myfield1=$2;getline;gsub(" ","");mystring=mystring$2" "myfield1", ";}END{print "set xtics ("mystring") and then ";}' grace.dat
您将获得以下输出：
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
对于第二部分：
awk 'BEGIN {FS=", *"}/tick major +[0-9]+/{myfield1=$2;getline;gsub(" ","");print "set arrow from "myfield1",Y11 to "myfield1",Y12 nohead"}' grace.dat
您将获得以下输出：
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
