===========================
Configuring the font family
===========================

You can explicitly set which font family is picked up for a given font
style (e.g., 'serif', 'sans-serif', or 'monospace').

In the example below, we only allow one font family (Tahoma) for the
sans-serif font style.  The default family is set with the font.family rcparam,
e.g. ::

  rcParams['font.family'] = 'sans-serif'

and for the font.family you set a list of font styles to try to find
in order::

  rcParams['font.sans-serif'] = ['Tahoma', 'DejaVu Sans',
                                 'Lucida Grande', 'Verdana']
