Many thanks for the quick and valuable return. I now use the _get_layout()
method and
it works like a charm :)
Just replaced:
sf1 = 6*72./txt1.cached.items()[0][1][1][0][1][0]
with:
sf1 = 6*72./txt1._get_layout('GTKAgg')[1][0][1][0]

Thanks Damon, it's very clear now. I explicit set the backend as "GTKAgg" in my ipython user configuration file. and always set the backend to 'Agg' in my rc file.

[Matplotlib-users] animation framework problem
Hi, I am trying to create a multi-subplot animation with based loosely on the animation example code, subplots.py, at http://matplotlib.sourceforge.net/examples/animation/subplots.html A simplified version of the full code is shown at this gist: https://gist.github.com/3613113 I am having problems getting the code to function properly. If I run it as is, the figure appears, but no animation is done. Apparently the setup code is called, but the code to change the frames is not. If I comment out the call to the setup code, the method to update the frame is called once, and that is it. I would appreciate any help and insights that you can provide.

It looks like you can either use the _get_layout() method (which requires that you specify the renderer), or, if you know the text object will be among the last 50 for which _get_layout() has been called, you can use txt1.cached[txt1.get_prop_typ()]. > > Is there a different way to achieve a fitted text object?

Hi Ben,
I changed the backend in matplotlibrc file. It works fine. Yet if I don't
want to change the rc file, I guess I must change in the modules where
matplotlib has been imported for the first time?
cheers,

[Matplotlib-users] Problem with text bounding box
Recently, I switched from matplotlib 0.99 to 1.0.1 and unfortunately discovered that my text scaling script stopped working properly. The script scales the given text to fit into the current figure. A quick example of what I'm doing (works in 0.99, but not in 1.0.1 and 1.1.1rc): import matplotlib.pyplot as plt plt.ion() fig = plt.figure(1, (6,8), dpi=72) fig.add_axes([0,0,1,1]) txt1 = plt.text(0.5,0.5,'foobar',horizontalalignment='center',verticalalignment='center') plt.draw() # compute width of figure in points and divide by txt1 bounding box width sf1 = 6*72./txt1.cached.items()[0][1][1][0][1][0] txt1.set_size(txt1.get_size()*sf1) plt.draw() The problem is related to the fact that starting from mpl 1.0.1, the txt1.cached dictionary contains information of all text objects present rather than only of the specific object. I guess this behavior is intended, however this way it is rather complicated to derive the bounding box of the specific text object without cycling over the whole dictionary. Is there a different way to achieve a fitted text object?
