Re: [matplotlib-devel] PR backlog -- ping us!

[Michael D. <md...@st...>]

Ideally, the example would be both:

   1) standalone under the examples tree so that it creates a gallery 
entry in the docs

   2) a regression test so that testing will ensure the feature 
continues to work over time

This isn't true of every PR, obviously, but for things that create nice 
new visible features it's a good rule of thumb.

As you probably know, we've got a lot of pull requests in the hopper.  
Thanks to everyone who's been triaging these lately.

I've just gone through and tried to add comments about what's left to be

[matplotlib-devel] Need some OS-X and Windows testing

[Michael D. <md...@st...>]

Just wanted to draw attention to some platform-specific pull requests 
that need some third-party  testing and comments from people on OS-X and 
MS-Windows.  If you're running on one of those platforms and able to 
build from git branches, it would be great to have some input:

OS-X:

Re: [matplotlib-devel] python 3 fork?

[Michael D. <md...@st...>]

2to3 is run on the source files in lib/matplotlib, which are then put 
under the build directory.  Think of it like a compilation step -- the 
original source files should never be touched.  You will need to install 
matplotlib (I recommend using virtualenv for this) in order to run it.

[matplotlib-devel] Added Phil Elson as a developer

[John H. <jd...@gm...>]

Phil Elson has been making pull requests for some time now on matters
great and small, from hairy transformations improvements to minor
docstring cleanups to GUI fixes.  Given his prolific work, I thought
it would be suitable to recognize him as a core matplotlib developer
by adding him to the github organization.  While the distributed
nature of the github system blurs the line between official and
regular developers, it is helpful to recognize those who make frequent
quality contributions and give them the permissions to merge pull
requests into the main repo.

Thanks for all your help Phil, and welcome aboard.

Re: [matplotlib-devel] python 3 fork?

[Tom L. <tom...@gm...>]

Hi All,

I've gotten it somewhat working.  For some reason the build process isn't pointing 2to3 at the files in lib/matplotlib.  But it's definitely running 2to3 on something..

Like the linked solution, I changed setupext.py to look for the dependencies in /usr/local.  I also made a new makefile and setupeggs which are changed in obvious ways.  The changes are on my github (tmlippman).

Rather than copy folders manually, I ran make twice:

	sudo make -f make.py3.osx PREFIX=/usr/local fetch deps

	sudo make -f make.py3.osx PREFIX=/Library/Frameworks/Python.framework/Versions/3.2 mpl_build mpl_install_develop

(outputs attached)

Everything appeared to compile fine, but when I tried to import matplotlib, I got errors like:  ImportError: No module named cPickle.

After running 2to3 on the lib/matplotlib directory (in my source location) everything works.

It would be great to convert that post in a pull request so it can be 
included upstream.  I'm not a Mac user myself, but I think there's 
enough Mac users to test that and push it through to make things easier

How did you try to use it? The released version doesn't support Python
3, but the development version on Github does. For Ubuntu, I've got a
daily-build PPA which includes python3-matplotlib:

Re: [matplotlib-devel] python 3 fork?

[Michael D. <md...@st...>]

The git master is compatible with Python 3, but it has not made it into 
a release.

Will be making at least one more 1.1.x bugfix release which will support 
Python 2.4 - 2.7 before making the next major release which will support 
Python 2.6 - 3.2.

I saw someone recently who'd managed to get it built for Python 3 on

Re: [matplotlib-devel] python 3 fork?

[Tom L. <tom...@gm...>]

I cloned the master branch on github and built it.  I'm on OS X 10.7, using the python 3.2 from python.org.  I installed fresh dependencies like in the osx makefile.  Then I had to run 2to3 on setupegg.py to get it to build.  Now when I try to import matplotlib in python3 I get a bunch of errors - e.g. it's looking for cPickle instead of pickle.

[matplotlib-devel] python 3 fork?

Hi All,

I saw that matplotlib had been ported to python 3 (here), and that the matplotlib-py3 branch was merged back into the main branch.  So I assumed matplotlib was compatible with python 3, and went ahead and tried to use it.  It didn't work.  Is there a different fork which is compatible with python 3?  What happened?

thanks,

Dan,

It is easy enough to remove the immediate roadblock in scale_range, but 
that just opens up a can of floating point worms.  The axis spines start 
getting misplaced, for example, as the range being plotted gets too 
small relative to the offset.  Straightening all this out, or even 
substantially improving it, is potentially tricky.  To the extent that 
it can be done, it will have to be in master, which already includes one 
cleanup of a floating point kluge.

Note that part of the problem here is that in your example we are 
running out of precision.  The best way to handle it is to subtract an 
offset first, and just plot the deviation from that offset.  I think 
this is best done at the application level.  We can probably make mpl's 
handling of the problem degrade more gracefully, however, than it does 
at present.

[matplotlib-devel] "Live Security Virtual Conference" ad

[Jason G. <jas...@cr...>]

I just noticed at the bottom of each message in a dozen or so that I 
checked from the last few days, I see an ad entitled "Live Security 
Virtual Conference".  I don't see these ads on messages in the 
sourceforge archive [1], but I do see them on the gmane mirror [2].  I 
also see the ad in a reply on the sourceforge archive [3].

I'm curious: Is this ad being put into outgoing messages by sourceforge, 
but not included in the archive (except when explicitly quoted in a 
reply)?  Or is there some other source for the ad?

Dan,

I think the behavior is coming from a threshold value of 1e-12 in 
ticker.scale_range.  This needs more thought than I can give it at the 
moment, but perhaps you could file a ticket on the github mpl site.

Note that even if this threshold behavior is removed, there is another 
one waiting in the wings behind it, with a default value of 1e-16, used 
to decide whether a range is singular; if it is, then it gets expanded.

[matplotlib-devel] plot() with a nearly-constant sequence doesn't always work

[Dan D. <dr...@ka...>]

Hello matplotlib developers,

In Sage, we've run into a problem with plotting a sequence whose
y-values change by very small amounts. Here's an example that doesn't
use anything from Sage:

import pylab
pylab.plot([0, 1], [0, 1e-14])
pylab.savefig("works.png")
pylab.close()
pylab.plot([0, 1], [1, 1+1e-14])
pylab.savefig("fails.png")
pylab.close()

We're using matplotlib 1.1. Here's a trac ticket where we are working on
this: http://trac.sagemath.org/sage_trac/ticket/11973. One of our
developers suspects matplotlib.ticker.MaxNLocator.bin_boundaries but we
don't really know.
