I've modified a local version of gnuplot_drawnow to take advantage
of these features. The first time a plot is drawn it works
correctly. When I place a loop around a plot command, the plot grows
progressively taller. It appears the each plot produces a window
which is taller by an amount approximately equal to 10 pixels.
Thus, figure(1) below is about 100 pixels taller than figure(2)
figure(1)
clf
for n=1:11
plot(1:10)
drawnow
endfor
figure(2)
clf
plot(1:10)
I'd like to be able to examine the entire gnuplot stream.
Unfortunately, if I replace "drawnow" with
drawnow ("x11", "/dev/null", true, sprintf("debug-%d.gp", n))
The plots render as would be expected.
In the unlikely event that someone has a recent build of gnuplot
4.3.0+ and a recent developers build for octave, I've attached a
path for gnuplot_drawnow that adds a single line to gnuplot_drawnow
and willl produce the effect I've described.
So my question is, can anyone describe what is changes for the
gnuplot stream in these two examples?

I've spent some time isolating the problem regarding the recently
committed a change to gnuplot that allows the x11 terminal to have
its size and position specified. The problem is not related to
Octave, but it is a problem if supporting the figure handle property
"position" is desired (which I've been working on).
Thus far, my exchanges with the gnuplot developers indicates that the
problem may be isolated to my system. I'm running Mac OSX 10.5.6 and
XQuartz 2.3.1 (xorg-server 1.4.2-apple17).
I'm hoping someone here is also running OSX and gnuplot 4.3.0+
(Revision > 1.2224.2.330). If so the following commands place
iteratively in a file produce a plot whose height iteratively grows
taller.
set terminal x11 size 560,480 position 440,106
set multiplot;
plot x
unset multiplot;
I've attached a file with the iterations. I'd be interested in what
other Mac OSX users get when the following is typed from the Terminal
window.
gnuplot -persist simple_example.gp Please let me know if the plot
grows taller and include your Mac OSX version, and the x-server
information.
