Re: Octave.app for MacOSX released

[Henry F. Mollet]

Below are lines 87-123 from drawnow.m where lines 109-114 are the
corrections that you had suggested that I use. I cannot paste the line #'s
into this post, therefore I'm also attaching the complete m-file.

function plot_stream = open_gnuplot_stream (h, term, file)

  ## If drawnow is cleared, it is possible to register __go_close_all__
  ## more than once, but that is not fatal.
  persistent __go_close_all_registered__;

  cmd = gnuplot_binary ();

  if (! isempty (h) && gnuplot_use_title_option ())
    cmd = sprintf ("%s -title \"Figure %d\"", cmd, h);
  endif

  plot_stream = popen (cmd, "w");

  if (plot_stream < 0)
    error ("drawnow: failed to open connection to gnuplot");
  else

    if (! isempty (h))
      set (h, "__plot_stream__", plot_stream);
    endif

     if (nargin == 3)
       fprintf (plot_stream, "set terminal %s\n;", term);
       fprintf (plot_stream, "set output \"%s\"\n;", file);
     elseif isempty(getenv("DISPLAY"))
       fprintf (plot_stream, "set terminal aqua %d\n",h);
     endif

      atexit ("__go_close_all__");
      __go_close_all_registered__ = true;
    endif

  endif
