Re: [Matplotlib-users] align title of subplot with ylabel

2010-05-19 Thread hettling 
Thanks for the suggestions, 'annotate' is what I need, I think.
I get errors though, also when I run the example scripts 
from here: 
http://matplotlib.sourceforge.net/trunk-docs/users/annotations_guide.html#using-complex-coordinate-with-annotation
 .

I get the error 'NoneType' object is not iterable when I try plt.show()
or try to save to eps.

So I am not sure if I have the correct version of matplotlib installed.
I checked out the newest matplotlib from the svn repository, removed my
current installed version and installed the version in the 'trunk/'
directory. 'annotate' did not work.
Later, I installed matplotlib from the '/branches/v0_99_maint'
directory. 
In both cases there were no errors in the installation, but still
'annotate' did not work.

Could it be that I have the wrong library from the svn repository
installed? Does r8319 mean release #8319? 

Kind Regards

Hannes

 While this is certainly possible with the released version, but it
 will require you to write a few tens of lines of code. Basically, you
 need create a custom Text class that update its position during the
 drawing time.

I haven't thought through the solution completely, but my intuition
says that this might be helpful:

http://matplotlib.sourceforge.net/examples/pylab_examples/anchored_artists.html
http://matplotlib.sourceforge.net/mpl_toolkits/axes_grid/users/overview.html#anchoredartists

These examples show ways of anchoring artists (like Text) to certain
locations. It's probably your best bet for getting what you want.
