 Hey there!
 I have a mac 10.9 (Mavericks), and I needed matplotlib for a course I was

 I installed python 2.7.6, as requested, and downloaded the installer (dmg)

 I created a simple file, to plot a simple graph, but then it gave me an error

 I don’t know what to do…
 Please help me.

Caio,
  Welcome to Python and matplotlib.  Unfortunately, we can’t (yet) answer your 
question.  I’m looking at your attached file on a Mac running Mavericks - and 
as far as I can tell it is completely blank.  You have avoided the most common 
error in posting to a python or python-related list, that is, your query is in 
plain text (thank you), but when you get an error message, would you please 
just cut and paste the whole traceback into your e-mail?

Thanks,
Bill

Dear B.,
thanks a lot for your replay. I get it.
What do you think is the measure for w and h. Is the unit of measure in
pixels?.
What does fps stand for?

Thanks a lot

 In your options to mencoder, you are specifying the width/height as:

 But your PNGs have size of 704x538 pixels. That's why you have black bars
 on either side of your animation.

Re: [Matplotlib-users] Example showing differences between Mac O$ and Windows use

2014-03-13 Thread Jeroen Hegeman
Hi Christophe,

This is (I think) a known limitation of the OS X backend. One way around this 
is to use another backend. Which backends are available depends on how your 
matplotlib was built. (And unfortunately I don’t know how to figure out which 
ones are available, apart from trying.) In my case (matplotlib from homebrew on 
OS X 10.9.2) the TkAgg backend works.

To use the TkAgg backend insert these two lines:
 import matplotlib
 matplotlib.use('Agg’)
before the line
 import matplotlib.pyplot as plt

I hope that helps.

Best regards,
Jeroen

That should be `matplotlib.use('TkAgg')`, not Agg. Agg is a
non-interactive backend, while TkAgg is an interactive Tkinter wrapper
around the Agg backend.

Jeroen seems to be right. The example runs fine in on my Mac when using the 
Qt4Agg backend (which is the default in my matplotlibrc file), but crashes when 
switching to the MacOSX backend. Tested on OS X 10.8.5., Matplotlib from 
MacPorts.

Best,

Re: [Matplotlib-users] Example showing differences between Mac O$ and Windows use

Well, there is a list in ~/.matplotlib/matplotlibrc (see 
http://matplotlib.org/users/customizing.html)

  CONFIGURATION BEGINS HERE
 
 # the default backend; one of GTK GTKAgg GTKCairo CocoaAgg FltkAgg
 # MacOSX QtAgg Qt4Agg TkAgg WX WXAgg Agg Cairo GDK PS PDF SVG Template
 # You can also deploy your own backend outside of matplotlib by
 # referring to the module name (which must be in the PYTHONPATH) as
 # 'module://my_backend'
 backend  : Qt4Agg

see also:

I'm not sure about the dependencies, I guess you have to check out each one of 
them. If you don't use a package manager, resolving all dependency issues might 
be quite painful.

Best,
Felix Patzelt

 Thanks a lot for this big hint but neither TkAgg works nor Qt4Agg can work 
 (because I do not have PyQt). 
 
 Is there a complete list of all the backends ?

Re: [Matplotlib-users] Example showing differences between Mac O$ and Windows use

2014-03-13 Thread Felix Patzelt
Are you sure that you want to use Python 3.3 on OSX 10.6??? Do you really still 
use 10.6? Do you want Python 3? I'm not sure on the current status, but many 
projects took quite a while to get ported over from Python 2. Furthermore, as 
often with free software, installation can be a bit tricky. It is certainly a 
very different experience than installing normal Mac applications. 

For a bit of context, most Linux distribution have some version of Python / 
Matplotlib in their respective package managers. These are easily installed if 
the particular package manager on your Linux offers the versions you want. 
Otherwise, you will have to do some work. 

OSX does not have an official package manager, but there are several inofficial 
options. I'm using http://www.macports.org which is slow because it installs 
its own private versions for everything, but it works very well. This is 
probably the easiest way to get all the open source stuff you want on your Mac 
and I use it a lot. Another popular and more lightweight package manager is 
homebrew, which relies more on the system libraries from Apple.

The minimal installation instructions without a package manager seem to be 
these: https://github.com/rueckstiess/mtools/wiki/matplotlib-Installation-Guide 
If you're a real unix hacker, you can install everything from source. I did 
that before, and it takes a lot of time and in-depth knowledge. 

Finally, there are several pre-packaged distributions like 
https://www.enthought.com or  https://store.continuum.io/cshop/anaconda/ (see 
http://penandpants.com/install-python/). They might come with a normal OSX 
installer. Maybe https://code.google.com/p/spyderlib/ does the trick for you? 

Anyway, these are just some suggestions. Maybe you want to start a separate 
thread on the mailing list about the best way to install matplotlib on a mac. 
Please note that I cannot comment in detail on any of the installation methods 
that I didn't use myself.

 Hello,
 is there any hope that the problems with animate will be fixed for Mac
 users ?


The only problem I'm aware of for Mac OSX is with blitting; blitting is
purely a performance optimization, so animations themselves should work
fine.

Is there something else I'm missing?

 The problems with animations on Mac

 with the MacOSX backend cannot be fixed
 without redesigning the animations module.

Can you give me a better idea why you think so? I wrote the original and have a 
Mac now...
