Summary: gnuplot set to multiplot mode in GUI Octave =>
gnuplot uses multiplot mode (qt driver) by default in GUI but chooses a driver
without multiplot in CLI

Follow-up Comment #1:
The issue is that some of the gnuplot backends don't work as well as others.
See this code in __gnuplot_drawnow__.m
## Work around the gnuplot feature of growing the x11 window and
## flickering window (x11, windows, & wxt) when the mouse and
## multiplot are set in gnuplot.
fputs (plot_stream, "unset multiplot;\n");
flickering_terms = {"x11", "windows", "wxt", "dumb"};
if (! any (strcmp (term, flickering_terms))
|| have_non_legend_axes (h)
|| numel (findall (h, "type", "image")) > 0)
fprintf (plot_stream, "%s\n", term_str);
if (nargin == 5)
if (! isempty (file))
fprintf (plot_stream, "set output '%s';\n", file);
endif
endif
fputs (plot_stream, "set multiplot;\n");
elseif (any (strcmp (term, flickering_terms)))
fprintf (plot_stream, "%s\n", term_str);
if (nargin == 5)
if (! isempty (file))
fprintf (plot_stream, "set output '%s';\n", file);
endif
endif
endif
if (! __gnuplot_has_feature__ ("dashtype"))
fprintf (plot_stream, "set termoption dashed\n");
endif
else
## gnuplot will pick up the GNUTERM environment variable itself
## so no need to set the terminal type if not also setting the
## figure title, enhanced mode, or position.
endif
Try setting the environment variable GNUTERM to your desired backend before
starting either the CLI or GUI version of Octave. If you choose the qt
backend you will find that multiplot is set in the CLI as well. Sample
session
~/wip/Projects_Mine/octave-stable: setenv GNUTERM qt
~/wip/Projects_Mine/octave-stable: octave-5.1.0 -f -q --no-gui
octave:1> graphics_toolkit gnuplot
octave:2> f = gcf();
octave:3> drawnow();
octave:4> stream = get(f, '__plot_stream__');
octave:5> fprintf(stream, 'show multiplot;\n');
octave:6> fflush(stream);
octave:7> multiplot mode is on
