thanks

Hello Matplotlib developers,
here below is a report a user of maplotlib sent to the Debian bug
tracker. I've verified and it happend also with 0.99.3:

$ python -c "import matplotlib as p ; print p.__version__"
0.99.3
$ python mpl_crash.py
terminate called after throwing an instance of 'char const*'
Aborted

Thanks for looking into it,
Sandro

It may be bad practice to add functionality this close to 1.0 release, 
but I couldn't resist.  The lack of an easy and interactive way to 
modify tick and tick label appearance parameters has seemed like a major 
shortcoming; manipulation of rcParams prior to creation of an Axes is a 
clumsy workaround.  My proposed solution, now in svn 8453, is the 
tick_params Axes method and pyplot function.  To see how it works, try 
the following in an "ipython -pyplot" session, pausing at each line to 
see the result:

plot([1,2,1.5])
tick_params(axis='x', colors='r')
tick_params(axis='y', color='pink', labelcolor='b')
tick_params(direction='out', length=6, width=3)
tick_params(labelright='on', labelleft='off', top='off')
tick_params(labelsize='large', pad=6)
tick_params(reset=True, colors='m')

I just tested it and it's very cool!  It works fairly quickly locally.  It
seems to work for Safari 5 and Chrome beta.  Firefox 3.6.3 is a no show.  I
haven't tried Opera.   What I'm really curious about is what is the latency
like over the actual internet, or under higher server loads (given the round
tripping).  For us, I'd have to try to get it to work for firefox (I think
as a cross platform browser, it's fairly common, especially on linux systems
like Fedora, it's what the user is most likely to have.).  Thanks for
sharing this!

Hello,

Our HTML5 based matplotlib backend is now available at:

http://code.google.com/p/mplh5canvas/

There are some basic installation instructions and included examples
to get going. Keep in mind that the weakest link at this stage is
browser support.

We recommend Chrome for the most hassle free experience.

This is very much a beta release and has not seen action outside of
our internal testing, so we expect some teething troubles :)

Please let us know what works for you, and what doesn't, and we will
try and fix things as they come up.

Cheers,

Simon and Ludwig

The issue was related with the change in Sphinx v1.0b2, which I think
I fixed in r8447.
At least, the html are built fine and uploaded fine.

However, the link to trunk-docs still does not work.

http://matplotlib.sourceforge.net/trunk-docs/

Can someone check what's wrong?

TIA,

-JJ
