ahah!  martin hit it spot on:  a "hold on" which i had previously
executed was at fault.

but now with further playing around i believe there is still a bug,
but this time in "hold on":

figure(1);
clf;
subplot(2,2,1);
plot([1 2 3]);
subplot(2,2,3);
hold on            % try w/ and w/o this line
plot([5 5 5]);
plot([4 5 6]);

i don't know to what extent you guys want/pursue matlab
compatability, but the behavior exhibited by the above script either
with or without the "hold on" statement does not mimic matlab.  more
importantly, the behavior *with* the hold on statement is clearly
not desirable, as it plots the data from all three plots in the
current subplot.

interestingly, when i run this script, either with or without the
hold on, i get the following warnings:

warning: in graw near line 10, column 2:
warning: graw is deprecated and will be removed from a future
warning: version of Octave.
warning: You should use the higher-level plot functions
warning: ("plot", "mesh", "semilogx", etc.) instead
warning: of the low-level plotting commands.
warning: If you absolutely must use this function, use the

as a reminder, this is with a standard fink install of 2.1.71 on
OS X 10.4.5 using X11.

thanks for the quick reply to my last query.  it's good to know
octave is being actively maintained.
