Hi,
You can do this by specifying the pos option when you create the
graph's key(...), also see
http://pyx.sourceforge.net/manual/module-graph.key.html.
In the case of a bottom-centered legend you then have something like:
# Initialize graph object
g = graph.graphxy(width=8, ratio=4./3, key=graph.key.key(pos='bc'))
# These are the data lines we want to plot.
data = [graph.data.file("data.dat", x=1, y=2, title="Data 1"),
graph.data.file("data2.dat", x=1, y=2, title ="Data 2")]
etc...
