No, once a plot is displayed new elements can't be added to
it. You can add new elements to a smartplot by drag-and-drop, but not by
Maple commands.

To plot a sequence of points, you build up a list or array of points and
then plot it.
Well, maybe there's a way to accomplish what you want, but it will require
resources outside Maple. It's most likely to be feasible on a Unix
system. What you'd want to do is set up a pipe from Maple to some other
process that can do incremental plotting, reading in points from the pipe
as they become available and plotting them.

Dear Gaurav,
it would be nice if this were possible, but so far it is not (to my
knowledge). After having left a plot statement you cannot reenter this
plot at a later occasion.
You already mentioned "display" that allows to circumvent the problem to
some extent.
The problem is (probably) that the plot-software of Maple has become
more and more "encapsulated" and primitive commands are (no longer)
accessible. As a student I enjoyed (among other things) to plot
potential curves of diatomic molecules with a frame of axis around. The
bottom axis in Bohr radii, the top axis in Angstroem, the left axis in
Hartree ans the right axis in electron Volts using a Calcomp plotter
with self.modified software. I wouldn't know how to do this in Maple (if
I had to).
This is probably part of a more general problem of a software producer:
Does he do research as his prime goal or does he wish to earn some
money. Maple is nowadays moving into the same direction as Mathematica.
But nevertheless I enjoy to use Maple and hence am carefully listening
to the heartbeat of my licence manager in order not to be cut off
unexpectedly.
All the best Jurgen
