From my computationa tool I am getting two plots one in xmgrace and other in some dat file format. The top few lines in xmgrace format (say it is a file grace.agr) is having tick lable and their positions which I want to use in my gnuplot script. My grace.dat lookes like (total ticklabels may be more here I am mentioning only few)
@ page size 595, 842
@ view 0.120000, 0.150000, 0.900000, 1.280000
@ default linewidth 2.0
@ xaxis label char size 1.5
@ xaxis ticklabel char size 1.25
@ yaxis label char size 1.5
@ yaxis ticklabel char size 1.25

With the help of grep, awk and some other tricks as mentioned in code section I managed to append below data in a file (say the file name is SETTICKS.dat)
cat SETTICKS.dat gives me this:
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, )

I want to use ticks and their positions from above mentioned grace.agr file at two places in the gnuscript as below
(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
where Y11 and Y12 are -10 and 10 respectively.
I propose you a solution just using awk.
For the first part:
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
you'll get this output:
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
For second part:
awk 'BEGIN {FS=", *"}/tick major +[0-9]+/{myfield1=$2;getline;gsub(" ","");print "set arrow from "myfield1",Y11 to "myfield1",Y12 nohead"}' grace.dat
you'll get this output:
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
