<h1>Introduction</h1>

<p>matplotlib is a python 2D plotting library which produces

publication quality figures in a variety of hardcopy formats and

interactive environments across platforms. matplotlib can be used

in python scripts, the python and <a

href="http://ipython.org">ipython</a> shell (ala

MATLAB<sup>®<a name="matlab" href="#ftn.matlab">*</a></sup>

Mathematica<sup>®<a name="mathematica"

href="#ftn.mathematica">†</a></sup>),

web application servers, and six graphical user

interface toolkits.</p>

<p align="center"><a href="users/screenshots.html"><img align="middle"

src="_static/logo_sidebar_horiz.png" border="0"

alt="screenshots"/></a></p>

<p>matplotlib tries to make easy things easy and hard things possible.

You can generate plots, histograms, power spectra, bar charts,

errorcharts, scatterplots, etc, with just a few lines of code.

For a sampling, see the <a href="users/screenshots.html">screenshots</a>, <a href="gallery.html">thumbnail</a> gallery, and

<a href="examples/index.html">examples</a> directory</p>

<p>For simple plotting the <tt>pyplot</tt> interface provides a

MATLAB-like interface, particularly when combined

with <tt>IPython</tt>. For the power user, you have full control

of line styles, font properties, axes properties, etc, via an object

oriented interface or via a set of functions familiar to MATLAB

users.</p>

<p>

On August 28 2012, John D. Hunter, the creator of matplotlib, died

from complications arising from cancer treatment, after a brief but

intense battle with this terrible illness. John is survived by his

wife Miriam, his three daughters Rahel, Ava and Clara, his sisters

Layne and Mary, and his mother Sarah.</p>

<p>

If you have benefited from John's many contributions, please say

thanks in the way that would matter most to him. Please consider

Fellowship</a>.</p>

<p>Trying to learn how to do a particular kind of plot? Check out

the <a href="gallery.html">gallery</a>, <a href="examples/index.html">examples</a>,

or the <a href="api/pyplot_summary.html">list of plotting

commands</a>.</p>

<h4>Other learning resources</h4>

<p>There are many <a href="resources/index.html">external learning

resources</a> available including printed material, videos and tutorials.</p>

<p>matplotlib is a welcoming, inclusive project, and we try to follow

the <a href="http://www.python.org/psf/codeofconduct/">Python Software

Foundation Code of Conduct</a> in everything we do.</p>

<p>Check the <a href="faq/index.html">faq</a>,

the <a href="api/index.html">api</a> docs,

<a href="http://matplotlib.1069221.n5.nabble.com/matplotlib-users-f3.html">mailing

list archives</a>, and join the matplotlib

mailing lists <a href="https://mail.python.org/mailman/listinfo/matplotlib-users">Users</a>,

<a href="https://mail.python.org/mailman/listinfo/matplotlib-announce">Announce</a> and

<a href="https://mail.python.org/mailman/listinfo/matplotlib-devel">Devel</a>.

Check out the matplotlib questions

on <a href="http://stackoverflow.com/questions/tagged/matplotlib">stackoverflow</a>.

The <a href="search.html">search</a> tool searches all of

the documentation, including full text search of over 350 complete

examples which exercise almost every corner of matplotlib.</p>

<p>You can file bugs, patches and feature requests on the

github

<a href="https://github.com/matplotlib/matplotlib/issues?sort=created&direction=desc&state=open">tracker</a>,

but it is a good idea to ping us on the mailing list too.</p>

<p>To keep up to date with what's going on in matplotlib, see

the <a href="users/whats_new.html">what's new

page</a> or browse the <a href="https://github.com/matplotlib/matplotlib">source

code</a>. Anything that could require changes to your existing code

is logged in the <a href="api/api_changes.html">api

changes</a> file.</p>

<h1>Toolkits</h1>

<p>There are several matplotlib add-on <a href="mpl_toolkits/index.html">toolkits</a>,

including a choice of two projection and mapping toolkits <a href="http://matplotlib.org/basemap">basemap</a> and

<a href="http://scitools.org.uk/cartopy/docs/latest">cartopy</a>,
