 for those using Lyx (a Latex frontend), I just noticed that the new 
 version (2.3.0) has support for gnuplot scripts. 
 I haven't really tested this myself yet,  
For those also interested: yes it does work.
Some more details, especially on Windows: You cannot directly use the 
gnuplot version bundled with gretl, unfortunately, see my comment in 
https://www.lyx.org/trac/ticket/11148#comment:5.
Maybe some kind of link called 'gnuplot' could be created to point to 
the wgnuplot.exe that comes with gretl, but I'm not sure how to do that 
on Windows. (Trivial batch file?) I just installed another gnuplot 
instance. On Linux I guess this isn't necessary.
And you can set Lyx's preferences yourself to recognize .plt as a 
gnuplot file, and then you can just write something like "gnuplot myvar 
--time-series" in your gretl script and the resulting file can indeed be 
used and inserted in the Lyx file.
(Of course if a lot of raw data are kept in that gnuplot source file the 
file size may be bigger than the corresponding pdf. AFAICS it makes 
sense mainly if you sometimes want a different output than pdf and/or if 
you are ready to edit the gnuplot source directly if changes are needed.)
