The legend module defines the Legend class, which is responsible for
drawing legends associated with axes and/or figures.

.. important::

    It is unlikely that you would ever create a Legend instance
    manually.  Most users would normally create a legend via the
    :meth:`~matplotlib.axes.Axes.legend` function. For more details on legends
    there is also a :doc:`legend guide </tutorials/intermediate/legend_guide>`.

The Legend class can be considered as a container of legend handles and
legend texts. Creation of corresponding legend handles from the plot elements
in the axes or figures (e.g., lines, patches, etc.) are specified by the
handler map, which defines the mapping between the plot elements and the
legend handlers to be used (the default legend handlers are defined in the
:mod:`~matplotlib.legend_handler` module).  Note that not all kinds of
artist are supported by the legend yet by default but it is possible to
extend the legend handler's capabilities to support arbitrary objects. See
the :doc:`legend guide </tutorials/intermediate/legend_guide>` for more
information.

loc : str or pair of floats, default: :rc:`legend.loc` ('best' for axes, 'upper right' for figures)
    The location of the legend.

    The strings
    ``'upper left', 'upper right', 'lower left', 'lower right'``
    place the legend at the corresponding corner of the axes/figure.

    The strings
    ``'upper center', 'lower center', 'center left', 'center right'``
    place the legend at the center of the corresponding edge of the
    axes/figure.

    The string ``'center'`` places the legend at the center of the axes/figure.

    The string ``'best'`` places the legend at the location, among the nine
    locations defined so far, with the minimum overlap with other drawn
    artists.  This option can be quite slow for plots with large amounts of
    data; your plotting speed may benefit from providing a specific location.

    The location can also be a 2-tuple giving the coordinates of the lower-left
    corner of the legend in axes coordinates (in which case *bbox_to_anchor*
    will be ignored).

    For back-compatibility, ``'center right'`` (but no other location) can also
    be spelled ``'right'``, and each "string" locations can also be given as a
    numeric value:

        ===============   =============
        Location String   Location Code
        ===============   =============
        'best'            0
        'upper right'     1
        'upper left'      2
        'lower left'      3
        'lower right'     4
        'right'           5
        'center left'     6
        'center right'    7
        'lower center'    8
        'upper center'    9
        'center'          10
        ===============   =============

bbox_to_anchor : `.BboxBase`, 2-tuple, or 4-tuple of floats
    Box that is used to position the legend in conjunction with *loc*.
    Defaults to `axes.bbox` (if called as a method to `.Axes.legend`) or
    `figure.bbox` (if `.Figure.legend`).  This argument allows arbitrary
    placement of the legend.

    Bbox coordinates are interpreted in the coordinate system given by
    `bbox_transform`, with the default transform
    Axes or Figure coordinates, depending on which ``legend`` is called.

    If a 4-tuple or `.BboxBase` is given, then it specifies the bbox
    ``(x, y, width, height)`` that the legend is placed in.
    To put the legend in the best location in the bottom right
    quadrant of the axes (or figure)::

        loc='best', bbox_to_anchor=(0.5, 0., 0.5, 0.5)

    A 2-tuple ``(x, y)`` places the corner of the legend specified by *loc* at
    x, y.  For example, to put the legend's upper right-hand corner in the
    center of the axes (or figure) the following keywords can be used::

        loc='upper right', bbox_to_anchor=(0.5, 0.5)

ncol : integer
    The number of columns that the legend has. Default is 1.

prop : None or :class:`matplotlib.font_manager.FontProperties` or dict
    The font properties of the legend. If None (default), the current
    :data:`matplotlib.rcParams` will be used.

fontsize : int or float or {'xx-small', 'x-small', 'small', 'medium', 'large', 'x-large', 'xx-large'}
    Controls the font size of the legend. If the value is numeric the
    size will be the absolute font size in points. String values are
    relative to the current default font size. This argument is only
    used if `prop` is not specified.

numpoints : None or int
    The number of marker points in the legend when creating a legend
    entry for a `.Line2D` (line).
    Default is ``None``, which will take the value from
    :rc:`legend.numpoints`.

scatterpoints : None or int
    The number of marker points in the legend when creating
    a legend entry for a `.PathCollection` (scatter plot).
    Default is ``None``, which will take the value from
    :rc:`legend.scatterpoints`.

scatteryoffsets : iterable of floats
    The vertical offset (relative to the font size) for the markers
    created for a scatter plot legend entry. 0.0 is at the base the
    legend text, and 1.0 is at the top. To draw all markers at the
    same height, set to ``[0.5]``. Default is ``[0.375, 0.5, 0.3125]``.

markerscale : None or int or float
    The relative size of legend markers compared with the originally
    drawn ones.
    Default is ``None``, which will take the value from
    :rc:`legend.markerscale`.

markerfirst : bool
    If *True*, legend marker is placed to the left of the legend label.
    If *False*, legend marker is placed to the right of the legend
    label.
    Default is *True*.

frameon : None or bool
    Control whether the legend should be drawn on a patch
    (frame).
    Default is ``None``, which will take the value from
    :rc:`legend.frameon`.

fancybox : None or bool
    Control whether round edges should be enabled around the
    :class:`~matplotlib.patches.FancyBboxPatch` which makes up the
    legend's background.
    Default is ``None``, which will take the value from
    :rc:`legend.fancybox`.

shadow : None or bool
    Control whether to draw a shadow behind the legend.
    Default is ``None``, which will take the value from
    :rc:`legend.shadow`.

framealpha : None or float
    Control the alpha transparency of the legend's background.
    Default is ``None``, which will take the value from
    :rc:`legend.framealpha`.  If shadow is activated and
    *framealpha* is ``None``, the default value is ignored.

facecolor : None or "inherit" or a color spec
    Control the legend's background color.
    Default is ``None``, which will take the value from
    :rc:`legend.facecolor`.  If ``"inherit"``, it will take
    :rc:`axes.facecolor`.

edgecolor : None or "inherit" or a color spec
    Control the legend's background patch edge color.
    Default is ``None``, which will take the value from
    :rc:`legend.edgecolor` If ``"inherit"``, it will take
    :rc:`axes.edgecolor`.

mode : {"expand", None}
    If `mode` is set to ``"expand"`` the legend will be horizontally
    expanded to fill the axes area (or `bbox_to_anchor` if defines
    the legend's size).

bbox_transform : None or :class:`matplotlib.transforms.Transform`
    The transform for the bounding box (`bbox_to_anchor`). For a value
    of ``None`` (default) the Axes'
    :data:`~matplotlib.axes.Axes.transAxes` transform will be used.

title : str or None
    The legend's title. Default is no title (``None``).

title_fontsize: str or None
    The fontsize of the legend's title.  Default is the default fontsize.

borderpad : float or None
    The fractional whitespace inside the legend border.
    Measured in font-size units.
    Default is ``None``, which will take the value from
    :rc:`legend.borderpad`.

labelspacing : float or None
    The vertical space between the legend entries.
    Measured in font-size units.
    Default is ``None``, which will take the value from
    :rc:`legend.labelspacing`.

handlelength : float or None
    The length of the legend handles.
    Measured in font-size units.
    Default is ``None``, which will take the value from
    :rc:`legend.handlelength`.

handletextpad : float or None
    The pad between the legend handle and text.
    Measured in font-size units.
    Default is ``None``, which will take the value from
    :rc:`legend.handletextpad`.

borderaxespad : float or None
    The pad between the axes and legend border.
    Measured in font-size units.
    Default is ``None``, which will take the value from
    :rc:`legend.borderaxespad`.

columnspacing : float or None
    The spacing between columns.
    Measured in font-size units.
    Default is ``None``, which will take the value from
    :rc:`legend.columnspacing`.

handler_map : dict or None
    The custom dictionary mapping instances or types to a legend
    handler. This `handler_map` updates the default handler map
    found at :func:`matplotlib.legend.Legend.get_legend_handler_map`.

        Parameters
        ----------
        parent : `~matplotlib.axes.Axes` or `.Figure`
            The artist that contains the legend.

        handles : sequence of `.Artist`
            A list of Artists (lines, patches) to be added to the legend.

        labels : sequence of strings
            A list of labels to show next to the artists. The length of handles
            and labels should be the same. If they are not, they are truncated
            to the smaller of both lengths.

        Other Parameters
        ----------------

        %(_legend_kw_doc)s

        Notes
        -----

        Users can specify any arbitrary location for the legend using the
        *bbox_to_anchor* keyword argument. bbox_to_anchor can be an instance
        of BboxBase(or its derivatives) or a tuple of 2 or 4 floats.
        See :meth:`set_bbox_to_anchor` for more detail.

        The legend location can be specified by setting *loc* with a tuple of
        2 floats, which is interpreted as the lower-left corner of the legend
        in the normalized axes coordinate.

        *legend_handler_map* should be a dictionary object (that is
        returned by the get_legend_handler_map method).

        It first checks if the *orig_handle* itself is a key in the
        *legend_handler_map* and return the associated value.
        Otherwise, it checks for each of the classes in its
