Using Dr. Douglas Eck's new mailing list search engine, a search for
"linear interpolation" finds:
http://www.idsia.ch/~doug/octave-lists/archives/help-octave-9504/msg00003.html
which may be able to help you with the linear interpolation.

Regarding the gnuplot, you can set the legend from within Octave with the
following syntax:

  plot (linspace(-4,4,40),sin(linspace(-4,4,40)),";Sine;")

Try "help plot" from within Octave for more information.
