Yes, when there is a plot window on the screen. But gnuplot_drawnow
begins with
function gnuplot_drawnow (h, term, file, mono, debug_file)
if (nargin < 4)
mono = false;
endif
if (nargin >= 3 && nargin <= 5)
## Produce various output formats, or redirect gnuplot stream to a
## debug file.
plot_stream = [];
fid = [];
printing = ! output_to_screen (gnuplot_trim_term (term));
unwind_protect
plot_stream = open_gnuplot_stream (1, []);
...
unwind_protect_cleanup
...
end_unwind_protect
elseif (nargin == 1)
## Graphics terminal for display.
plot_stream = get (h, "__plot_stream__");
if (isempty (plot_stream))
plot_stream = open_gnuplot_stream (2, h);
...
and open_gnuplot_stream is:
function plot_stream = open_gnuplot_stream (npipes, h)
cmd = gnuplot_binary ();
if (npipes > 1)
[plot_stream(1), plot_stream(2), pid] = popen2 (cmd);
if (pid < 0)
error ("drawnow: failed to open connection to gnuplot");
endif
else
plot_stream = popen (cmd, "w");
if (plot_stream < 0)
error ("drawnow: failed to open connection to gnuplot");
endif
endif
if (! isempty (h))
set (h, "__plot_stream__", plot_stream);
endif
endfunction
So we only use popen2 when output is to the screen. Should we just
always use popen2? I can't remember the reason for sometimes using
popen.
