[Maxima] Questions about draw and gnuplot

I am trying to develop some interactive tools for use with draw2d.
Anyone know the answers to the following questions?
1. Where does maxima store the data for a plot? I know how to a file,
and I can do some mininal things with those coordinates, but I want to
do more. I don't know where the whole plot data is stored.
2. Does anyone have examples with the "keypressed" command in the
gnuplot interface to draw2d?
I want to click on a point in the graphics window, say with mouse
button 1, keep the mouse down, drag it to another point and when it is
released, see a line segment added to the existing plot. Then, with a
keypress, I want to have an action done to the plot. For instance, have
the line segment mapped with a pre-existing function to a parabola. I
want to have the existing plot remain with the line segment and the
parabola added to it.
These are similar to some very basic things available in the drawing
program xfig. I would like to use maxima to implement some similar
things with draw2d.
Any ideas or suggestions would be appreciated.
