[SciPy-user] wxWindow_GetClientSizeTuple problem using plt.plot

[David Humphrey]

Yesterday, I installed

SciPy-0.2.0_alpha_144.4350_src.tar.gz
wxPython 2.3.3.1 for Python 2.2
wxWindows 2.2.9
Numeric 22.0

I've had Python 2.2.1 from www.python.org installed for several weeks.

On a Windows NT 4.0 SP6a machine.  I spent some time getting used to SciPy
as I have some prior experience with each of the other packages.  At the
moment, I'm interested in plt.plot().  While I've been able to get a few
simple 2-D plots to work, I'm having a proble with the following code
residing in the file test2.py:

import gui_thread
from Numeric import *
from scipy import plt
from scipy import *

binz = array([-162., -126., -90., -54., -18.,  18.,  54.,  90., 126.,
162.],Float)
countz = array([ 9006, 1621, 26248,  2912,  7096,  8537,  1533, 22517,
1224,  6563],Float)
plt.plot(binz,countz)

When I execute this script, I get the following results:

$ python test2.py
<wxPython imported>
>>>

    val = apply(windowsc.wxWindow_GetClientSizeTuple,(self,) + _args,
_kwargs)

Exception exceptions.TypeError: "'NoneType' object is not callable" in

Can anyone tell me what I'm doing wrong?
