Plotting points in 3D?



I know this can be done in plain gnuplot, but can it be done from
within Maxima, using plot3d?   I'm just playing around with dynamical
systems, and I have set up the (discrete) equations to generate the
Lorenz attractor.  And now I'd like to plot the points they produce.

I *can* do it with "dataplot" from the "descriptive.mac" share file,
but I wonder if I can do it in some other way...

Another, related plot question: I generated the plot for the Henon
attractor (in 2D) by first generating the lists of all the points, and
then plotting them.  But can the plotting be done more interactively -
that is, each new point produced being added to the plot?  This would
certainly save memory, as I wouldn't have to generate large lists
first.

Same thing for 3D data plots.

Thanks,
