It occurs to me to ask if you are already familiar with the following
Axiom commands:

vp1:=draw(sin(x), x=%pi/10..%pi)
g1:=getGraph(vp1,1)
pointLists(g1)
...
g2:=makeGraphImage(lineSegments, lineColors, pointColors, lineSize)
pointLists(g2)

See for example

Perhaps uidraw is producing output similar to this?
