matplotlib-users Mailing List for matplotlib (Page 3)

One possibility is that with v1.3, we changed how packaging was done.
Unfortunately, this did cause some transitional issues. The best bet is to
uninstall *all* versions of matplotlib, pylab, and mpl_toolkits first, then
re-install v1.3.1. Note that waiting for the v1.4 release wouldn't
necessarily solve anything as it is the transition *from* older versions of
matplotlib that is the issue rather than transitioning *to* newer versions.

Hopefully this helps,
Ben Root

matplotlib 1.3.1 works quite well with python 2.7.

I never recommend pip to Windows users (at least not until everything is in
wheels).

The last few times I had no problem `easy_install`ing the matplotlib exe
installer in a virtualenv, nor any of the other exe installers.

(pip is for Linux users, I never found anything better than easy_install on
Windows.)

Hello dydy,

If you've never done programing in python I would recommend a book
"dive into python" any version will do but the latest one is 3 I
think. Asking this questions in tut...@py... will probably
get you even further since they mainly deal with general python
learning.

Whatever you can use through command prompt you can use in python if
you use import subprocess. Subprocess.call("command") calls whatever
command you want over the command line. If you can call IDL to run
files over command line this can be an option. If not you're going to
have to use a wrapper tool like SWIG is foc c/c++ or another module to
connect to IDL. A useful module here will usually be os as well.

As for installations of modules under windows platforms, that's always
tricky, I recommend using a virtualenv with pip, because then
generally installing a module boils down to using "pip install". But
even in virtualenv on windows I've had issues with installing i.e.
matplotlib and found it impossible and I've had to install it
system-wide by using one of the unofficial binary installers from:
http://www.lfd.uci.edu/~gohlke/pythonlibs/ and from then I have to
start start each virtualenv with the option --system-site-packages
which kind of defeats the purpose of a virtualenv, but such is the
nature of developing on win's....
(I've read that you can activate local modules by hand, but I've not
been able to reproduce it)


I know this is a bunch of new info, I suggest you read up on it, best of luck,
Dino

Hey, even I had similar issue.
Later I learnt python2.7 could support matplotlib version1.0.1 only.

So if you want to upgrade your matplotlib, you first need to upgrade your
python.

Hello all,

I interested in python programming that is why I join in this forum.
I want to know how to install new module in my python program?. I use python
under windows OS.
Actually, I interest with PyNio but I don't know how to install it.
Another question is how to make other language, for example, IDL, can be
read in python?
Thank you....

Dydy

Adding a caption to a plot inserted with the `plot` directive from mpl's
sphinxextensions does not work for me, even though the [documentation][1]
says it should be possible.

The relevant ReST snippet:
```

    :alt: 'Schematic drawing of the two solution methods'

    Schematic drawing showing the two possible solution methods discussed.

I don't see a reference in the documentation saying it's a feature that was
added in a newer version of mpl.

What am I doing wrong?

I installed using version 1.3.1 windows binary
"matplotlib-1.3.1.win32-py2.7.exe" from mathplotlib download. Installation
went fine, but when using the package, it says "dateutil" and "pyparsing"
are missing, which are supposed to be bundled according to the installation
instruction. Is this a bug or expected behavior from now on? I did not have
this issue for earlier versions of matplotlib.
My base python is 2.7.8.

If anyone is having the issue, either download the binaries from pythonlibs
mentioned above, or
install from the sources, which I did as follows:
(1) Install setuptools if you don't have it. 
    Download source from https://pypi.python.org/pypi/setuptools;
    Unpack and run 'ez_setup.py install'; or 'python ez_setup.py install'
    This will install setuptools.
    
(2) Install any other package by downloading the source, unpacking, and 
    running 'setup.py install'
    e.g., "dateutil" has been installed this way.
    https://pypi.python.org/pypi/python-dateutil, same for pyparsing

It's better to use the static libraries for libpng, zlib, and freetype 
(unless you have reasons not to). Rename the .lib files as in the build 
script:

I am still trying to build matplotlib on windows. The instructions on 1717
were very helpful, I managed to build the
prerequisites manually based on the instructions in the dep_build.cmd that
came from matplotlib-winbuild project.

ImportError: DLL load failed: The specified module could not be found.

I am guessing it doesn't like the filename of the png16.dll file, but how
do I know what filename it is looking for?
I noticed I had to rename a bunch of .lib files in order to build
matplotlib from source, but that was OK since the error message
said what file it was looking for. How do I determine the correct filename
to use from here?
