Ideally you should create a routine which returns the lines you
want to draw, and leave it to another routine to do the
plotting.  That allows flexibility in choosing a plotting

If you need to do the plotting from C++, I would
recommend using feval to call the usual plot scripts
rather trying to tie directly into the stream.  Something like:

  #include <octave/parse.h>
  octave_value_list in;
  in(2) = "x;my line;";
  in(1) = Y;
  in(0) = X;
  feval("plot",in,0); // nargout==0

My question in a nutshell is this.  From a dynamically linked
function, how do I create graphics?  There is a
send_to_plot_stream() in pt-plot.cc but its symbol is not
exported, except through the graw() function.  I see that there
are structures, tree_plot_command, etc., but I don't understand
what to do with them.  And I can't seem to trace from plot.m ->
__plt__.m --> __plt2__.m --> to the point where it interfaces
with the C++ code.
