Default legend handlers.

.. important::

    This is a low-level legend API, which most end users do not need.

    We recommend that you are familiar with the :doc:`legend guide
    </tutorials/intermediate/legend_guide>` before reading this documentation.

Legend handlers are expected to be a callable object with a following
signature. ::

    legend_handler(legend, orig_handle, fontsize, handlebox)

Where *legend* is the legend itself, *orig_handle* is the original
plot, *fontsize* is the fontsize in pixels, and *handlebox* is a
OffsetBox instance. Within the call, you should create relevant
artists (using relevant properties from the *legend* and/or
*orig_handle*) and add them into the handlebox. The artists needs to
be scaled according to the fontsize (note that the size is in pixel,
i.e., this is dpi-scaled value).

This module includes definition of several legend handler classes
derived from the base class (HandlerBase) with the following method::

    def legend_artist(self, legend, orig_handle, fontsize, handlebox)

    A Base class for default legend handlers.

    The derived classes are meant to override *create_artists* method, which
    has a following signature.::

      def create_artists(self, legend, orig_handle,
                         xdescent, ydescent, width, height, fontsize,
                         trans):

    The overridden method needs to create artists of the given
    transform that fits in the given dimension (xdescent, ydescent,
    width, height) that are scaled by fontsize if necessary.

        Return the artist that this HandlerBase generates for the given
        original artist/handle.

        Parameters
        ----------
        legend : `~matplotlib.legend.Legend`
            The legend for which these legend artists are being created.
        orig_handle : :class:`matplotlib.artist.Artist` or similar
            The object for which these legend artists are being created.
        fontsize : int
            The fontsize in pixels. The artists being created should
            be scaled according to the given fontsize.
        handlebox : `matplotlib.offsetbox.OffsetBox`
            The box which has been created to hold this legend entry's
            artists. Artists created in the `legend_artist` method must
            be added to this handlebox inside this method.

        Parameters
        ----------
        patch_func : callable, optional
            The function that creates the legend key artist.
            *patch_func* should have the signature::

                def patch_func(legend=legend, orig_handle=orig_handle,
                               xdescent=xdescent, ydescent=ydescent,
                               width=width, height=height, fontsize=fontsize)

            Subsequently the created artist will have its ``update_prop``
            method called and the appropriate transform will be applied.

        **kwargs
            Keyword arguments forwarded to `.HandlerBase`.
