There are some instances where you have data in a format that lets you

:class:`numpy.recarray` or :class:`pandas.DataFrame`.

Matplotlib allows you provide such an object with
11+
the ``data`` keyword argument. If provided, then you may generate plots with
12+
the strings corresponding to these variables.
