How to draw a line

Scripting Issues
1

I need to draw a simple line from one 3d point to another.

self.segs = LineSegs("lines");
self.segsnode = self.segs.create(False)
render.attachNewNode(self.segsnode)
self.segs.setColor(1,1,1,1)
self.segs.drawTo(-1, 3, 0)
self.segs.drawTo(1, 2, 1)

any clue why nothing shows up?
are there some convenience functions for doing this or am I going about it right?
