Sorry for the long delay. I've been on vacation an offline.

Try the PointSet DrawObject:
MyPoints = Canvas.AddPointSet(coords, Color="red", Diameter=4)
coords is a sequence of coordinates, either a numpy array or anything
that can be turned into one:
( (x1,y1), (x2,y2), ....)
note that you can change properties of objects without deleting and
re-creating them:
MyPoints.SetColor("blue")
