Dear Mico,
while we do have a pyxrc facility for some PyX configuration, such
configuration options will only contain maschine dependend
information. I'm strongly against using a gobal config file for layout
adjustments as your PyX scripts would silently become dependend on the
local configuration.
Instead it is a common practise to use a Python script itself for
configuration. In your case I suggest to build you a file containing
stuff like
from pyx import *
class myaxis(graph.axis.lin):
def __init__(self, ...):
pyx.graph.axis.__init__(self, ...)
You can than use PyX by importing your PyX configuration and use
mygraph, myaxis, etc.
