Maybe this is some help to you.
My question to you is: How do you add such a command to your compiler?
(I wouldn't know where to start, I'm only using Linux for 3 months now)
(Disclaimer: I have not tried this myself, since I don't use gnuplot.)
First, you obviously need to have gnuplot installed and working.
In LyX, go to Tools > Preferences > File Handling > Converters and
select (highlight) the "LaTeX (pdflatex) -> PDF (pdflatex)" converter.
In the "Converter:" entry, change "pdflatex $$i" to "pdflatex
--shell-escape $$i" and save it. See if that helps.
If it does, you might consider a fancier solution. You could go to
Tools > Preferences > File Handling > File formats and create a new
format (let's call it "PDF (with plots)"), then back to ... > Converters
and create a "LaTeX (pdflatex) -> PDF (with plots)" converter using the
converter syntax above (and return the first converter to its original
syntax). You would then use "View > PDF (with plots)" rather than "View
> PDF (pdflatex)" to view files with gnuplots in them (and similarly
with file export). The reason for doing this would be security -- it
would allow shell escapes only for documents where you knew you needed
them. FWIW, I think the low security approach is pretty safe unless you
have a habit of including raw LaTeX files from unverified sources in
your documents.
