I think the easiest solution is to pass a manual tick at 0 -- and label
that with an empty string:
# -*- coding: utf-8 -*-
from pyx import *
g = graph.graphxy(width=5, height=5, xaxisat=0, yaxisat=0,
x=graph.axis.lin(min=-1,max=1,manualticks=[graph.axis.tick.tick(0,label="")]),
y=graph.axis.lin(min=-1,max=1,manualticks=[graph.axis.tick.tick(0,label="")]))
g.writePDFfile("test")
With that approach, PyX calculates automatic ticks and labels, but takes
the tick "0" without label into account.
HTH,
Axel
