Maybe you can try skipping SVN altogether (needs "git-cvs" package on 
Ubuntu):

export CVSROOT=/rsynced/directory
test -d "$CVSROOT/CVSROOT" || echo "Wrong cvsroot..."
mkdir imported
cd imported
git cvsimport matplotlib

This at least shows some files in the first revisions. You can probably 
then just graft the two histories together at a suitable point.

Apparently, it also needs some use of "git filter-branch" to get rid of 
the top-level matplotlib/ directory.

Sourceforge just enabled enough access to get a copy of the cvs
repository by doing:

rsync -av matplotlib.cvs.sourceforge.net::cvsroot/matplotlib/* .

So, if I have the cvs repo in a local directory called "mpl.cvs", then I can do:

cvs2svn --encoding=utf_8 -s mpl.svn mpl.cvs

Unfortunately, I am getting exactly the same results: the matplotlib/
directory is missing in the earliest history. I've tried adding
--use-cvs and --keep-trivial-imports, to no avail. I've tried checking
out a working copy of the cvs repo (setting CVSROOT to point to the
directory I created using rsync), and I *thought* the right way to
inspect the r7 working directory is to do "cvs update -R -r 7", but
thats not right. So I'm currently having trouble determining whether
the history even exists in CVS. Anybody have a longer memory than I
do? How can I get cvs to perform this basic operation?

Fantastic, many thanks!  For anyone who is willing to shepherd this
through inclusion in MPL, I *strongly* recommend they read the paper
in the link above, titled:

“Stacked Graphs – Geometry & Aesthetics” by Lee Byron & Martin Wattenberg.
PDF link: http://www.leebyron.com/else/streamgraph/download.php?file=stackedgraphs_byron_wattenberg.pdf

In fact, I'm sure anyone who's intrested enough in data viz to be on
this list would tremendously enjoy the paper, it's a really good
piece.

Unfortunately I'm too swamped to fully help you move this through, but
a few pointers now so to get you going, and hopefully another core dev
can pitch in...

- For mpl inclusion, your code needs to be explicitly BSD licensed,
and should mention that the original code it's based on (if you read
any of the implementation) was also BSD licensed (which it is, as per
this file: https://github.com/leebyron/streamgraph_generator/blob/master/COPYRIGHT).

- I read your implementation and it looks very nice and concise,
excellent job.  After reading the paper, I was just wondering if this
problem might not benefit from a bit of object orientation...

I'm just thinking out loud here, and I actually tend to always favor
holding of on the OO until a more decoupled, functional approach shows
its limitations.  So perhaps your take is just fine for now.  But what
I'm thinking about is that the Streamgraph construction has a number
of moving parts:

* the optimization formulation to select g_0.
* the colormap choices, which can be fairly sophisticated.
* the sorting of the time series and their assignment on the stream stack.

It might be more convenient to bundle all these into an object that
exposes the already implemented options and can be extended to other
algorithms.  This is a case where I'm thinking of going OO not because
of inheritance, but simply as a way of grouping related functions and
data in a way that's easier to pass around in more complex codes.

In fact, a good solution might be to keep a number of standalone
functions and offer a wrapper object that exposes an OO interface.
For simple cases people could just call the function with some data,
but for more complex development using (and possibly extending) the
object would be cleaner.

In any case, I hope this feedback is useful, and I look forward to
streamgraphs in MPL!  Sorry that I won't be able to work on the
review/merge itself in the future; as interested as I was by the paper
(many thanks for bringing it to our attention), I'm already neglecting
other things far too much :)

Regards,

f

Maybe someone has already done this?  (Thanks to whomever it was!)

It looks like the download links all point to 1.0.1 now.

Marshall,

Welcome!  I'm sorry my first reply was a bit curt, especially 
considering that you are offering a patch. We do appreciate 
contributions.  A little discussion may be required as to the future 
strategy for keyboard shortcuts, but thank you for getting started.

In my opinion, having it enabled by default is a horrible idea--it is 
too easy to hit it accidentally, and when one does so, the consequence 
is too damaging.  The present default-enabled shortcuts are bad enough; 
I am tempted to change the defaults--but maybe more people would be 
displeased than pleased by that change.

My dim recollection is that we don't presently have support for anything 
other than the normal keys.  I don't know what is involved in adding it.

I hope Michiel de Hoon can reply regarding backend_macosx specifics.

I'm pretty sure that if it is within mpl, it would be in backend_macosx. 
  It is not the sort of thing I would expect to have changed, though. 
Again, Michiel de Hoon may be able to shed light on this.

I'm guessing only the admins can change this (or at least I
didn't find a way to do it myself on the sourceforge site) but
the link at the top of the download page still points to 1.0.0

"Loking for the latest version? Download matplotlib-1.0.0.tar.gz"

This actually affects all of the direct download links that are
scattered about (the one on the project summary page, for example) 

Can someone with the privileges points it to 1.0.1?

best,
