The code changed in this area but I don't know how, in 1.4.0cvs > 2. Put copies of the previous two attachments, eps.gnuplot and > ascii.gnuplot into any directory that contains Gnuplot plot > files. My solution for this problem is a script that wraps the call to gnuplot, and adds the necessary declaration for output. Usually I enter also a preamble with some of the default values for my drawings. > 3. Make each Gnuplot plot file (*.gnu) self-contained.

Interestingly in some of their examples they use .plt I have been using gnp, but I guess that it is a question of personal taste here. :-) > 3. I only care about the LaTeX format.

You can gnuplot to the graphic supported formats. :-) -- José Abílio LyX and docbook, a perfect match. :-)
