The simplest way in Java is probably to use a Gridded2DSet (or 3D) with
a manifold dimension of one -- just put your x,y (and probably z if you
are using 3D and want to put it above your background). This would be
your 'data' use use to make a DataReference which then gets added to
your display. The MathType would be a RealTupleType of the RealTypes
for each of your domain coordinates.
In Jython, you might just use:
subs.drawLine(display, points, color=, ... )
where 'points' is a list/tuple of your coordinates, defined in
terms of the types mapped to the x,y,z axes, respectively...like:
( (x0, x1, x2,x3),(y0, y1, y2, y3),(z0, z1, z2, z3) )
Hope that helps,
