I confess I'm surprised because this feature was disabled by default. I 
had to manually enable it whenever I made a binary installer by editing 
setup.cfg.

I build the Mac binaries using bdist_mpkg. I'm afraid I don't know how 
it works under the hood. It creates an "mpkg" binary installer in the 
dist subdirectory. To run tests, I install matplotlib (using that mpkg 
installer), since there isn't an obvious way to tests on the mpkg.
I'm sure it's possible to accumulate all the files as you suggest and 
turn them into a binary installer, but I don't know how to do it.
Is it useful in the long term to have such a packager? My impression is 
that as soon as packaging is more robust we'll switch to using pip or 
easy_install.

The old matplotlib was not using .pth files (at least I never found any 
in site-packages).

That is an interesting suggestion. I"m not an expert, but I thought mpkg 
files usually didn't know how to uninstall old files (though one can add 
scripts to do this).

That's a good idea. And we skip it on other platforms ;)

Thanks. It's using nose under the hood, so that's exactly what I 
meant. I should have been more clear.
I'm not sure what might be causing this. As a sanity check (and maybe 
you've already done this), have you tried doing "rm -rf matplotlib*" in 
your site-packages directory?

It also made it impossible to install security updates in those other 
packages, which was a problem for Linux distros, MacPorts, homebrew, etc.

I thought that was the solution we had arrived at in the earlier 
discussion. I'm sorry if I misunderstood. If you "python setup.py 
install" matplotlib into a fresh virtualenv, it will install all of 
these dependencies. Then that virtualenv's site-packages directory can 
be used as the basis for the contents of the installer. As I'm not a 
Mac guy, and I don't understand how the installer is built, is there a 
reason that wouldn't work?

Have you investigated how that's happening? There are no components by 
that name in the current matplotlib, so they shouldn't be touched, 
unless the old matplotlib was using .pth files for them or something, I 
suppose, but I don't think it was by default. Have you investigated 
what exactly the installer is clobbering? Maybe take a snapshot of the 
site-packages tree before the installer and then using a tree diffing 
tool to see what the differences are afterward.

I think we need to get to the bottom of why it's breaking the old 
installations of pytz and dateutil. Then we can hopefully address 
that. Does the installer try to uninstall what the old installer 
installed first, perhaps?

Yes.
All the interesting information about a build is printed at the 
beginning and soon scrolls out of sight, so it's usually not obvious if 
a build is missing something expected.
That seems to be standard for unix and distutils installers, so I 
suspect it would not be trivial to change. Would it make sense to add a 
unit test that verifies the mac backend was built?

I ran nosetest in matplotlib in site-packages. That produces the 
following result:

I have appended my test log. I don't know how to run the tests using 
nose, but will be happy to have a go with instructions. (Running 
"nosetests" in the matplotlib source dir does nothing useful).

matplotlib used to include pytz and dateutil in its installation. This 
seemed to be a very good thing overall, since it made sure the 
dependencies were satisfied, though it is possible that it occasionally 
overwrite a version the user would have preferred to have.
In any case the matplotlib developers removed support for this feature 
in 1.3. As a result, binary installers now have to tell users to install 
these packages manually (as well as six and pyparsing). It may be 
possible to postprocess the Mac binary installer to install these 
packages, but I don't know how to do it.
The problem is that under some circumstances the new installer may trash 
existing installations of python-dateutils and pytz. I consider that 
unacceptable. Why break things that are already installed?
In other words, we seem to have the worst of the old world and the new: 
don't install the new packages but perhaps break them if they already 
exist. Unfortunately breakage is likely to be the norm because most 
users will be upgrading from matplotlib 1.2.1.

The layout has changed, but sidebar has not. Can you provide a 
screenshot? Note, you can always visit the older version of the website 
at http://matplotlib.org/1.2.1 for direct comparison.

What do you mean the unit tests are missing? They don't run? Can you 
send the output from nose?
Glad to hear about the installer building the macosx backend -- that was 
pretty serious when it wasn't doing that.

I thought you were including pytz and dateutils in your installer. Is 
that not the case? If not, isn't it enough to document that matplotlib 
now doesn't ship with these dependencies, and they will need to be 
installed using pip or other means? Can they be installed afterward and 
have things work?

The main matplotlib.org website's layout seems different. What used to 
be in the sidebar now seems to be in the middle of the page, and the 
example images spill into the sidebar. Is this a mistake or is it 
supposed to be that way?

I built the Mac binary on MacOS X 10.6 but have run into two problems:
- Most of the unit tests are missing, so I can't properly test the 
results. But my application that uses matplotlib and TkAgg works fine, 
so may well be OK. Also, I checked and the installer was trying to build 
all expected backends (including the native Mac backend).
- When the 1.3.0 installer is used to overwrite matplotlib 1.2.1 (and 
the pytz and dateutil that it installs) it breaks pytz and dateutils, by 
deleting most of the contents, leaving only a subdir named zoneinfo in 
each package (with different contents for each package).
Installing a new pytz and dateutils and running the 1.3.0 binary 
installer (overwriting matplotlib 1.3.0 or no matplotlib at all) leaves 
these packages functional (though it changes the modification date, so 
it's doing something).
I have replicated this several times.
I'm not sure whether to upload this installer. It's a bit dangerous and 
ill tested.

That will be fine for now, and it sounds like Nelle will make the

That contains the output of the Sphinx document I used to generate the

Hello,
At Scipy, we briefly discussed the possibility of having the nicest plots
of the John Hunter Excellence in Plotting Contest on matplotlib's website,
with the code available.
I personnally would love to be able to see those plots again, and the code
used to generate them. It would also be a great way to advertise the use of
matplotlib for high standard plotting.
I would love to work on this. I was thinking that the easiest would
probably to do a dedicated website, where we could easily upload the code,
the data and the images in high resolution. It would also allow us to have
a more modern looking website, more "commercial" than the matplotlib one.
Also, we (matplotlib) do not hold the copyrights but I think scipy or
numfocus does. Hence, doing this in the name of scipy (or numfocus) would
avoid some legal issues.
We could then be able to link to this website.
What do you think?
(We should also include the organizers of the contest in this discussion,
but I don't really know how to contact them.)
Cheers,
N

As promised in last week's Google Hangout to the IPython developers 
meeting -- I have some concrete timings and numbers on the matplotlib 
WebAgg backend in a couple of different scenarios.
First, let me apologize -- the way I was timing binary websockets vs. 
text websockets previously was wrong. The actual impact of it is much 
smaller than I had originally estimated -- so the discussion about 
whether to include binary websockets in IPython may have been all for 
naught.
For benchmarking, I used two different plots. One is the classic 
"simple_plot.py" sine wave, which tests sort of the "easy case" where 
very little of the image is updated in each frame, and the other was 
"animation/dynamic_image.py" in which most of the plot is updated in 
each frame.
I tested both scenarios with client and server on my local machine, and 
through an ssh tunnel that goes over wifi, the public university 
network, to my home's 15/5 MBps cable connection 28 miles away and back.
For (A), the average frame weighs in at around 20kb. For (B), it's 
around 90kb. For base64, multiply by those numbers by 4 / 3.
On my local machine, I can push through about 18 fps, so a bandwidth of 
2.8MBps (were it sustained, which it rarely is). On the tunnel, I 
fluctuate between 7 and 10 fps, which is quite usable, and quite near 
the practical upper limit on the bandwidth of that connection.
However, the problematic thing for the remote connection is the 
latency. Locally, I average a fairly steady 250ms to roundtrip from a 
mouse event to an updated frame. Remotely, it fluctuates randomly 
between 400ms (still usable) and 3000ms. Some more careful dynamic 
scaling of events can probably make that easier to use, perhaps. I know 
games often use UDP and handle robustness to packet loss in a different 
way as a way to remove some of the latency of TCP. I have no idea if 
such a thing would be possible over a web socket, of course.
I could not measure any statistically significant change in framerate or 
latency between a binary websocket and a non-binary one. However, there 
is a 10% increase in CPU time on both the python side and the browser. 
It so happens that I wasn't saturating my CPU, so it had no net impact. 
Likewise, I am not saturating my bandwidth, so the additional size 
doesn't matter in this case. But I suspect if either one of those 
resources is starved, the additional 10% cpu time and 25% bandwidth 
increase may matter.

I suspect what changed is you don't include it anymore (but I would have

I am building a binary installer, so I don't use "python setup.py 
install". I use bdist_mpkg, which presumably does something similar to 
"python setup.py build" and packages the results (without installing 
them).
In any case, I need to know which packages matplotlib needs so I can 
warn users to install them in the binary installer's ReadMe file. The 
list is rather long. I miss having this stuff included in matplotlib. At 
this point I know of the following (aside from numpy):
- python-dateutil (unfortunately matplotlib complains about missing 
"dateutil" if it's absent; it would help to give the name of the package 
as known by pip, rather than what is imported)
- pytz
- six

I'm not sure how to diagnose this, but if you have any ideas, let me 
know. (Though I should probably read the rest of the messages on this 
thread before saying that.)

https://github.com/matplotlib/matplotlib/issues/2243
The above issue raises the question of whether the default for aspect 
ratio handling should be "datalim" instead of "box". The big advantage 
is that this completely avoids the problem described in the issue, where 
setting aspect='equal' can result in an unusable aspect ratio in screen 
coordinates.
For one common use of equal aspect--images--it is essential to have the 
adjustable be "box". I suspect that in most other use cases, "datalim" 
would be a satisfactory default.
The problem with a change like this is how to make the transition 
without wreaking havoc on existing code. The typical answer is to use 
an rc parameter, starting with the existing default, and then switching 
it over in some subsequent release.
Any thoughts? Should we leave all this as it is, or try to change it?
Eric

I've been a bit quieter on the Matplotlib side lately, but since
I'm now full-time on IPython, I wanted to pipe in that I, too,
can act as a conduit. Not only for the dev meeting, but in

I think Fernando's too busy to monitor this list closely, so you

Ah, that makes sense. Hopefully as part of doing some automated Mac

Thanks.

The output of running "python setup.py build" passes by quickly, and people (including myself) did not notice that the MacOSX backend was not being compiled.
And then if an older version of matplotlib is already installed, everything seems to be working fine.
I noticed this problem today only because I was installing matplotlib on a new Macbook.

We could update the makefile so that make clean really cleans up the
installation "junk" before installing a new version. I personnally would
find it very useful, but the makefile needs a bit of love. Typically "make"
would run make clean and make install.
I can work on that if people agree that having a nice makefile would be
useful.

Part of this is due to the change to setuptools/distribute,
 Even though I was the one who spearheaded the move
to setuptools, I'm wondering whether we shouldn't examine backtracking
on some of this for the 1.4.x release.
I don't think so--in this case the timing was particularly bad, but the
core developers are pretty commited to setup tools/pip as the way of the
future, so these things will settle down.
And just like MPL has issues because many of us wait for "final" to test (
guilty as charged...) the distribution tools need to be tested by complex
packages like MPL in order to get robust and stable.

The second issue is more one of process. When I make a release
candidate, I announce it here, and Cc all of the packagers of the major
Linux distributions, as well as Christoph and Russell who put together
packages for Windows and Mac respectively. Part of that delegation is
because I don't have installations of all of those platforms, and part
is to spread some of the workload. And most of the time it works really
well -- a big thanks to everyone involved. However, this cycle there
have been a small number of critical bugs discovered in the fifth
release candidate that existed in the first release candidate, which
doesn't give me a lot of confidence that final won't have critical bugs
either. I think some of this will be ameliorated over time as we build
out a more effective continuous integration infrastructure (see MEP19:
we could really use some help on this one), but some of it may have to
do with users being unwilling to test a release until it has the word
"final" attached. How can we get more ordinary users (who may have even
more unusual environments) involved? I also suspect some of it has to
do with the timing in the summer which hits in the middle of vacations
and conference travel for many. We can certainly avoid the summer
months next time. But I don't think it's just about building more time
into the schedule. Let me know if I'm doing something boneheaded ;)

Same with me. I had a stale pyparsing.pyc file in the MPL source directory
(presumably from an old MPL version) whose version # was too old. When mpl
tried to 'import pyparsing', it found that version, and raised an error. Of
course, if I tried "import pyparsing; print pyparsing.__version__" from my
home directory, python found a more recent pyparsing. So the error message
was a little confusing.
I only think this is going to effect people building from the Git source,
who have the old pyparsing.pyc file.
