matplotlib: no interactive window shown

Question

>>> from pylab import *
>>> plot(1)
[<matplotlib.lines.Line2D object at 0x2a9f9ce550>]
>>> show()

Nothing happens. No error message. No interactive window.

Someone know what's the problem could be?

The OS is RH4 and DISPLAY is set properly. Other GUI application can work fine.

maybe you mpl backend is not properly set ? I have no clue what this could be. Do other mpl codes work? — oz123, Dec 12 '11 at 06:18
Other functionalities work fine. For example, I can successfully create PNG graphes. — limi, Dec 12 '11 at 06:26
so why do you need an empty plot to appear ? does figure() work ? — oz123, Dec 12 '11 at 09:04
RH4 ? Is it python 2.4 ?. Is the last mpl version fully compatible with your python ? — joaquin, Dec 12 '11 at 13:51
Does the same thing happen if you run that same example code as a python file (instead of typing it into the interpreter)? — Joe Kington, Dec 13 '11 at 20:57

Oz123 is right, this can be caused by the wrong backend being set "svg","ps", and "cairo", for example, don't seem to support show() see this post for examples of how to change it, get "GTKcairo" working if it's not, or change the default
