Hi, I am trying to use matplotlib non-interactively but if I don't have DISPLAY set then wx barfs even though I have tried forcing the backend, etc..
eg..
[midget 16:51] ~/projects/beermon >python
Python 2.5.1 (r251:54863, Aug 14 2007, 11:27:14)
[GCC 3.4.6 [FreeBSD] 20060305] on freebsd6
Type "help", "copyright", "credits" or "license" for more information.
>>> import pylab, matplotlib
matplotlib.use>>> matplotlib.use('agg')
>>> fig = pylab.figure()
Traceback (most recent call last):

7352, in _BootstrapApp
return _core_.PyApp__BootstrapApp(*args, **kwargs)
SystemError: wxEntryStart failed, unable to initialize wxWidgets! (Is DISPLAY
set properly?)
Same problem if I try Cairo.
I had a google but no luck, can anyone help me out?
Thanks.
