matplotlib-devel Mailing List for matplotlib

Hello
I don't know why it is failing with the macports... not much help
about that from me ;)
If I make it fail on pourpuse, for example adding and unwanted int
third argument in the plot call
import matplotlib
matplotlib.use('gtk3agg')
from numpy import *
from matplotlib.pyplot import *
x = arange(0,10,0.1)
plot(x, sin(x), 0)
show()
The method FigureManagerGTK3.destroy() is being called twice, and
because it calls
self.__dict__.clear()
the second time it is called, it does not find any attribute, and that
is the reason for the UGLY message that hides the real problem. In my
example it is hiding the
ValueError: third arg must be a format string
Actually there is a comment on the line asking why is it called there...
In gtkagg there is a bunch of hasattr calls in the destroy method just
to bypass this problem
Is there any reason for the
self.__dict__.clear() ????

Y yo que culpa tengo de que ellas se crean todo lo que yo les digo?

Hello all,
I just upgraded my matplotlib and gtk distributions because I thought 
I'd try the GTK3Agg backend (I had been using the GTKAgg backend).
I'm using macports for the supporting libraries with git repositories 
for ipython and matplotlib (today's master [0b8481977016e8f], but I seem 
to have the same issues with tag v1.3.x)
Before installing matplotlib, I did a make clean and then removed 
everything from the build/ directory, and matplotlib* from
python2.7/site-packages/
The following ports are currently installed:
 gtk2 @2.24.17_1+x11 (active)
 gtk3 @3.10.0_0+x11 (active)
 py27-gobject3 @3.8.3_0 (active)
 py27-gobject @2.28.6_0 (active)
If I use the GTKAgg backend I get these warnings (which I did not get 
before).
===

In [1]: x = arange(0,10,0.1)
In [2]: plot(x,sin(x))

Otherwise everything else seems ok.
If I use the GTK3Agg backend, I get no plot window when I do a show(), 
and when I attempt to exit ipython, I get these errors:
===
object? -> Details about 'object', use 'object??' for extra details.
