You're right. This doesn't create a linked axis. But it doesn't help a
bit. Compiling the stuff I get the error:

Just for the record. The following code does what I want:
from pyx import *
d = graph.data.list([(1, 0.3),
(2, 0.5),
(3, -0.3),
(4, 0.8),
(5, 0.5)], x=1, y=2)
mypainter =
graph.axis.painter.regular(basepathattrs=[style.linewidth.THIck])
g = graph.graphxy(width=8,
x=graph.axis.lin(painter=mypainter,
linkpainter=mypainter),
y=graph.axis.lin(painter=mypainter,
linkpainter=mypainter))
g.plot(d, [graph.style.line()])
g.writeEPSfile("xy_axis")
