subsequent figures close immediately

[Earth]

Run something like this

#!/usr/bin/python
import pylab

for i in range(1,3):
 X = [1,2]
 Y = [i,2]
 pylab.plot(X,Y)
 pylab.show()

It should show a figure. When you close its window, a second figure will be plotted in a new window.

In intrepid: the second window closes immediately.
Should happen (happens on other platforms): the second window stays open.

if you want a single figure with 2 plots in it, then move pylab.show()
out ot for loop.

This is because pylab.show() displays the first image (the one with
diagonal line) and wait for you to close the popped-up window. Once
done, the loop goes into the second (and last) iteration, and show the
second plot in a different picture.

With GTKAgg backend it works correct, but with TkAgg backend the second window closes immediately. matplotlib 0.98.5.2-1ubuntu2 is still affected.

matplotlib 0.98.5.3-1ubuntu1 is still affected.

I'm still having this bug in ubuntu natty beta...
jens@morpheus:~$ apt-cache policy python-matplotlib
python-matplotlib:
  Installed: 0.99.3-1ubuntu2
  Candidate: 0.99.3-1ubuntu2
  Version table:
 *** 0.99.3-1ubuntu2 0
        500 http://archive.ubuntu.com/ubuntu/ natty/universe amd64 Packages
        100 /var/lib/dpkg/status

workaround with gtkagg does work

using

import matplotlib
matplotlib.use('GTKAgg')
import matplotlib.pyplot as pylab

instead of import pylab makes it work

[WeatherGod (ben-v-root)]

Don't import matplotlib.pyplot as pylab. This will only serve to cause confusion as the pylab interface is different from the pyplot interface. You should only need to do the first two lines (and they should be before any other matplotlib imports).

In addition, because Natty *should* come with matplotlib v1.0.1 (fingers crossed), this bug should become irrelevant as the problem in TkAgg has long since been fixed.

Thanks Julian!
