plotting a spline

Gnuplot can do smoothing via splines.  I think You'll need to
communicate directly with gnuplot using graw() rather than any of the
Octave plot() routines:

  d = rand(20,1);
  plot(d);  #raw version
  save -ascii '/tmp/d' d;
  graw("plot '/tmp/d'  smooth csplines\n")  #smoothed version


For more help on gnuplot smoothing, start gnuplot then do:

  gnuplot> help smooth
