Clearing and reusing a figure
===============================

``fig.clf()`` (or ``fig.clear()``) drops every axes and figure-level
decoration but keeps the figure's ``figsize``/``Style`` -- handy for redrawing
into the same ``Figure`` object rather than constructing a new one each time
(e.g. a live dashboard). ``fig.delaxes(ax)``/``ax.remove()`` does the same for
a single axes without wiping the rest of the figure.
