A quick look at Matplotlib and related libraries

One of Matplotlib’s most important features is its ability to play well with many operating systems and graphics backends. Matplotlib supports dozens of backends and output types, which means you can count on it to work regardless of which operating system you are using or which output format you wish. This cross-platform, everything-to-everyone approach has been one of the great strengths of Matplotlib. It has led to a large userbase, which in turn has led to an active developer base and Matplotlib’s powerful tools and ubiquity within the scientific Python world.

We will use the plt.style directive to choose appropriate aesthetic styles for our figures. Here we will set the classic style, which ensures that the plots we create use the classic Matplotlib style:


.. code-block:: pycon

    plt.style.use('classic')

The available styles are listed in 


.. code-block:: pycon

    plt.style.available


The basic way to switch to a stylesheet is to call


.. code-block:: pycon

    plt.style.use('stylename')

But keep in mind that this will change the style for the rest of the session! Alternatively, you can use the style context manager, which sets a style temporarily


.. code-block:: pycon

    with plt.style.context('stylename'):
        make_a_plot()
