[Matplotlib-users] GUI neutral animation example doesn't work with WxAgg/Wx
The GUI neutral animation example from the SciPy cookbook doesn't seem
to work for Wx or WxAgg backends. A plot window opens but nothing
happens. It appears to be some weird problem with ion on wx.
For example, the following code will run and immediately close:
plt.ion()
plt.plot(x, y)
plt.show()
After removing plt.ion(), a plot window is opened and the program
doesn't end until the window is closed (as expected).
If I use TkAgg or Qt4Agg (the only other GUI backends I have
installed) the examples (above and below) work as expected.

Full Example:
#
import matplotlib
matplotlib.use('WxAgg')
import matplotlib.pyplot as plt
import numpy as np
plt.ion()
x = np.arange(0, 2*np.pi, 0.01)
line, = plt.plot(x, np.sin(x))
for i in np.arange(1, 20):
line.set_ydata(np.sin(x + i/10.0))
plt.draw()
#
PS. This seems to work the same on both trunk and 0.98.3.

I need to update the cookbook, but if you want to do it that would be great as I am short on time until next week. The examples in examples/animation are the recommended way: http://matplotlib.sourceforge.net/examples/user_interfaces/index.html I have spent some time working on abstracting the necessary parts, eg the idle handler, but have not completed this across interfaces.

Sorry I'm still a student---I need guidance. ;) -Tony - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100url=/ ___ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users
