  <h1>intro</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.scipy.org">ipython</a> shell (ala matlab or
  mathematica), web application servers, and six graphical user
  interface toolkits.</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="{{ pathto('users/screenshots') }}">screenshots</a>, <a href="{{ pathto('gallery') }}">thumbnail</a> gallery,  and
<a href="examples/index.html">examples</a> directory</p>

  <p align="center"><a href="{{ pathto('users/screenshots') }}"><img align="middle"
  src="{{ pathto('_static/logo_sidebar_horiz.png', 1) }}" border="0"
  alt="screenshots"/></a></p>


  <p>For example, to generate 10,000 gaussian random numbers and make a
  histogram plot binning the data into 100 bins, you simply need to
  type</p>

  <pre>
  >>> from pylab import randn, hist
  >>> x = randn(10000)
  >>> hist(x, 100)</pre>

  <p>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&reg; users.
  The pylab mode provides all of the <a href="api/pyplot_api.html">pyplot</a> plotting
  functions listed below, as well as non-plotting functions from
  <a href="http://scipy.org/Numpy_Example_List_With_Doc">numpy</a> and
  <a href="api/mlab_api.html">matplotlib.mlab</a>.</p>
