Dear Group,

I am trying to enumerate few interesting errors on pylab/matplotlib. 
If any of the learned members can kindly let me know how should I address them.

I am trying to enumerate them as follows.

i) >>> import numpy
>>> import pylab
>>> t = numpy.arange(0.0, 1.0+0.01, 0.01)
>>> s = numpy.cos(2*2*numpy.pi*t)
>>> pylab.plot(t, s)
[<matplotlib.lines.Line2D object at 0x021122D0>]
>>> pylab.show()
Exception in Tkinter callback

The example above works for me just fine (in ipython):
In [1]: import pylab

In [2]: import numpy

In [3]: t = numpy.arange(0.0, 1.0+0.01, 0.01)

In [4]: s = numpy.cos(2*2*numpy.pi*t)

In [5]: pylab.plot(t, s)
Out[5]: [<matplotlib.lines.Line2D at 0x3c36310>]

In [6]: pylab.show()  # At this point a plot of cos(t) appears as expected


Have you customised your matplotlibrc file? I have no problems with the above,

Sorry, I don't have this module installed.

I think the problem is with the OS. In my home machine(with MS-Windows 7) it is running fine, but in the office machine(with MS-Windows XP SP2) it is giving error. I tried to have a word with my System Admin friend he is bit unaware about the Python environment, and I have a pressing need to solve. I restarted the machine but did not help. 

Regards,
Subhabrata.

I think you'd get more responses if you post your questions on the 
matplotlib users mailing list.
