matplotlib-users Mailing List for matplotlib

Hi everybody. Question about multiple Y axes...
I've seen a few posts regarding using the trick of laying one axes over top of the other to simulate a second Y axis -- as demonstrated in the matplotlib example file two_scales.py.
However, in the application I'm building, the user should be able to select points ("outliers") for either axis. With the current approach, the user can't select the bottom graph's points (or pan or zoom it).
Is there a way to bring the bottom graph into "focus"?
Thanks in advance for any tips.

The egg was compiled with numpy 0.9.6, which is what needs to be used.
 The Matrix error looks familiar. Try searching the list archive.

I just tried, really just from curiousity, to install the 0.87.2 egg on 
my Kubutu 5.10 laptop, with numarray 1.5.1, numpy latest SVN, ipython 
latest SVN. Setting numerix to numpy in matplotlibrc results in a 
segmentation fault when doing "ipython -pylab". Setting numerix to 
numarray results in a long traceback the end of which reads:
 File 
"/usr/lib/python2.4/site-packages/matplotlib-0.87.2-py2.4-linux-i686.egg/matplotlib/artist.py", 
line 4, in ?
 from transforms import identity_transform

"/usr/lib/python2.4/site-packages/matplotlib-0.87.2-py2.4-linux-i686.egg/matplotlib/transforms.py",

ImportError: No module named Matrix
If I download the tarball and build it from source, all is well.
