<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>
or
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
making a donation to
the <a href="http://numfocus.org/johnhunter/">John Hunter Memorial
Fund</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>
<h4>Need help?</h4>
<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 <a href="http://sourceforge.net/mail/?group_id=80706">lists</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>, the more detailed <a href="_static/CHANGELOG">changelog</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>,
3d plotting with <a href="mpl_toolkits/mplot3d/index.html">mplot3d</a>,
axes and axis helpers in <a href="mpl_toolkits/axes_grid/index.html">axes_grid</a> and more.
</p>
<h1>Citing matplotlib</h1>
<p>
matplotlib is the brainchild of John Hunter (1968-2012), who, along with its many
contributors, have put an immeasurable amount of time and effort into producing a
piece of software utilized by thousands of scientists worldwide.
If matplotlib contributes to a project that leads to a scientific publication,
please acknowledge this work by citing the project. You can use this
<a href="citing.html">ready-made citation entry</a>.
