======================
Plotting with keywords
======================

There are some instances where you have data in a format that lets you
access particular variables with strings. For example, with
:class:`numpy.recarray` or :class:`pandas.DataFrame`.

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