"GNU"..? Well, please: language, platform? What's the problem? Not how to read your own file, I hope?... :-)

Solution 1

you can use gnuplot script file. example:

1- edit set_title.plot with notepad:
notepad <path>\set_title.plot
set title 'my_title'

2- in gnuplot:
>load '<path>\set_title.plot'

I don't know if a direct way exists for what you want (maybe shell escape??). But actually, it can be done via os shell scripting. for example using bash:
assume that file.1 contains 'part1', file.2 contains 'part2', then:
$ echo set title \'$(cat file.1) $(cat file.2)\' > 1.plot
prepares your gnuplot script.
You can search it as 'gnuplot shell escape' as a starting point.
