The discussion of pipes and transfering data from Octave to gnuplot should go to 
the Octave list.  Octave currently sends data to gnuplot though a pipe.  The 
Octave folks may be able to help you set something up in terms of transferring 
data and the type of plot you'd like to generate.

I've also update the patch

[ gnuplot-Patches-1027032 ] Connect gnuplot_x11 to exterior application window

which uses a pipe created using TCL rather than C, but I see now that isn't 
anything you need.
