The following example works for me with PyX 0.7:

#!/usr/bin/env python
from pyx import *

data = [ [ (1, 1), (2, 2), (3, 3) ], [ (1, 1), (2, 4), (3, 9)] ]

g = graph.graphxy(width=10)

g.plot([graph.data.list(date, x=1, y=2) for date in data],
       [graph.style.symbol(symbol=graph.style.symbol.changecircle)])

g.writeEPSfile("test")

[ Btw: Please always send a complete example to show that something doesn't
work as it should. This way it's much easier for others to test it. ]
