This is used in interactive mode to update a figure that
has been altered using one or more plot object method calls;
it is not needed if figure modification is done entirely
with pyplot functions, if a sequence of modifications ends
with a pyplot function, or if matplotlib is in non-interactive
mode and the sequence of modifications ends with :func:`show` or
:func:`savefig`.
This is used in interactive mode to update a figure that has been
altered, but not automatically re-drawn. This should be only rarely
needed, but there may be ways to modify the state of a figure with
out marking it as `stale`. Please report these cases as bugs.

A more object-oriented alternative, given any
:class:`~matplotlib.figure.Figure` instance, :attr:`fig`, that
was created using a :mod:`~matplotlib.pyplot` function, is::

fig.canvas.draw_idle()
