Magic is the operative word.  It is sprinkled like pixie dust throughout 
mpl.  You may be able to figure it out by looking at the code for other 
functions that do support units.  You could look for recent commits by 
Ted Drain, if I remember correctly, and by John, both of whom fill gaps 
in units handling every now and then.

For example, note this line at the top of scatter:

         self._process_unit_info(xdata=x, ydata=y, kwargs=kwargs)

Looks like this is better handled by fill_between, nevermind.

Now, what about dates?  I'm having problems using dates for the x-axis for 
fill_between.  I know I can use date2num on my array, but I was wonder if there 
was some magic I could add to the fill_between code.

I think the reason is that it is not obvious what any filled region with 
masked vertices should look like.

Hi,

Is there any reason pyplot.fill() doesn't support masked arrays?  Or was it just 
overlooked?

Getting git-svn installed without root privileges is truly epic, given 
there are virtually no installation instructions for it, and its 
homepage seems to be down.  This doesn't bode well for git-svn adoption 
in managed environments like mine where users don't have root.  In 
fairness, the hard bit is Subversion and its perl bindings, but those do 
need to be current, and the commonly available advice to install 
Alien::SVN using cpan is totally broken for non-root installs.  I hope 
that the git-svn guys can simplify this down the road...

So, I thought I'd share my solution here to save others the trouble...

###Don't use cpan to install Alien::SVN -- it should have made this 
whole thing really easy, but it has a number of known bugs when 
installing without root.###

Here's what worked for me.  I have a folder ~/usr for my usual 
user-local installs, that's already been set up with the usual 
environment variables in my .bashrc:

   export PATH=~/usr/bin:$PATH
   export LD_LIBRARY_PATH=~/usr/lib:$LD_LIBRARY_PATH
   export PKG_CONFIG_PATH=~/usr/lib/pkgconfig:$PKG_CONFIG_PATH

1) Download and install openssl from www.openssl.org/source

   tar zvxf openssl-0.9.8i.tar.gz
   cd openssl-0.9.8i
   ./configure --prefix=/home/mdroe/usr
   make -j
   make install

2) Download subversion tarball

   cd ..
   tar jxvf subversion-1.5.4.tar.bz2
   cd subversion-1.5.4

3) Download neon inside the subversion source tree, and configure

    wget http://www.webdav.org/neon/neon-0.27.2.tar.gz
    tar zvxf neon-0.27.2.tar.gz
    mv neon-0.27.2 neon
    cd neon
    ./configure --prefix=/home/mdroe/usr --without-gssapi --with-ssl=openssl

4) Get apr and apr-util, and configure

    svn co http://svn.apache.org/repos/asf/apr/apr/branches/0.9.x apr
    cd apr
    ./buildconf
    cd ..
    svn co http://svn.apache.org/repos/asf/apr/apr-util/branches/0.9.x 
apr-util
    cd apr-util
    ./buildconf
    cd ..

5) Build subversion

    ./autogen.sh
    ./configure --prefix=/home/mdroe/usr --with-ssl --enable-shared
    make -j
    make install

6) Build perl bindings

    make swig-pl
    make swig-pl-lib
    make install-swig-pl-lib
    cd subversion/bindings/swig/perl/native
    perl Makefile.PL PREFIX=/home/mdroe/usr
    make install
    cd ../../../../../..

7) Download, build and install git

   tar zvxf get-1.6.0.tar.gz
   cd git-1.6.0
   ./configure --prefix=/home/mdroe/usr
   make install


... follow Andrew Straw's git instructions ... (???) ... profit!!!

I updated the documentation to hopefully address the issue that John
(and Michael) had. I also moved the git documentation to a section in
doc/faq/installing_faq.rst.

And I noticed that github does automatic parsing of rst files. Check
this out -- Sweet! :)
http://github.com/astraw/matplotlib/tree/master/doc/faq/installing_faq.rst#install-from-git

Note that there is a section called "A note about git write access"
which outlines an issue we may want to address, but probably only after
some familiarity with the issues involved. For now, for me, even a
one-way sync of the svn repo is a huge win for looking at history
locally and doing "git bisect". (And "one-way sync" doesn't give justice
to the ease of committing to the svn repository from git.)

Great -- everyone please hold off adding any significant features
before the release and focus any mpl time you have on outstanding
bugs.

Works for me.  Let's aim for Saturday night so we have Sunday to test
it out.  Doable?

Hi John,

Michael just wrote me that he got the same error. I think that perhaps I
need to assign write permissions even to read using the "personal" URL.
For now, can you try the public clone URL
git://github.com/astraw/matplotlib.git instead? I will attempt to sort
this out... (And of course give you and Michael and anyone else write
permissions if need be.) I'm new to git in a multi-developer context and
 git-svn may add another layer here, so please bear with me.

Just got an account, but am getting a permission denied on the first
command.  I tried both with the "git" and "jdh2358" users:

home:~> git clone gi...@gi...:astraw/matplotlib.git mpl.git
Initialized empty Git repository in /Users/jdhunter/mpl.git/.git/
ERROR: Permission to astraw/matplotlib denied to jdh2358.
fatal: The remote end hung up unexpectedly

Permission denied (publickey).

Has anyone had any success installing git-svn on a managed machine 
without root priviledges?  It seems that the Perl Alien::SVN dependency 
is totally broken in that context.

Despite my occasional recent murmurings to get a release out, which
fall by the wayside as more pressing matters arise, I really would
like to do a 0.98.4 ASAP.   Part of the reason is that there are lots
of great features and bug fixes that should be more easily accessible
to others (in particular Jae-Joon's fantastic work), part of the
reason is that the website gallery is getting farther apart from the
last released version, and part of the reason is that I am giving a
talk on Dec 12th to the NIPS "machine learning and open source
software" (MLOSS) conference.

John Eaton, of Octave fame, is the other invited speaker to this
session, and I want to put our best face forward.

I would like to do the release this weekend if Charlie has time
(Charlie?).  So please get your bugfixes and cleanups in over the next
couple of days, and let me know if there are any other critical
show-stopper problems or critical bugs that should hold up the
release.

And if you have any extra time to spend taking out a few bugs on the
tracker over the next couple of days, that would be great.

I just put my git mirror of the matplotlib svn repository online. This
is experimental in nature. Thanks to github for hosting this project.
Anyhow, I added instructions for how to use this (including to interact
with the central svn repository) here:

http://github.com/astraw/matplotlib/tree/master/README.git

Note that the initial downloads are about 150 MB in size.

I have not actually used git in collaboration with others save through
the svn interface, so I don't have experience with some aspects of git,
particularly collaborating branching/merging/pushing etc. For
single-user use, however, I've been finding all that stuff very nice.
One thing particularly useful is the ability to clean up history before
committing changes to a central subversion repository.

Anyhow, thanks to Ondrej for the critical clue for how to make this work.
