To subscribers of the xforms list from Andrew Szymkowiak <> :

We would like to add points to an xyplot without re-drawing the
previously drawn points. We are using xforms for a real-time display
task, to plot data points as they arrive. I would guess that we are
not the first to desire this, so I thought I would ask the mailing
list if someone else has come up with a way to do this (using the
xforms axis, scaling and drawing routines rather than issuing our
own low-level X calls to draw on a canvas).
Thank you,
