Container classes for `.Artist`\s.

`OffsetBox`
    The base of all container artists defined in this module.

`AnchoredOffsetbox`, `AnchoredText`
    Anchor and align an arbitrary `.Artist` or a text relative to the parent
    axes or a specific anchor point.

`DrawingArea`
    A container with fixed width and height. Children have a fixed position
    inside the container and may be clipped.

`HPacker`, `VPacker`
    Containers for layouting their children vertically or horizontally.

    Pack boxes specified by their ``(width, xdescent)`` pair.

    For simplicity of the description, the terminology used here assumes a
    horizontal layout, but the function works equally for a vertical layout.

    *xdescent* is analogous to the usual descent, but along the x-direction; it
    is currently ignored.

    There are three packing *mode*\s:

    - 'fixed': The elements are packed tight to the left with a spacing of
      *sep* in between. If *total* is *None* the returned total will be the
      right edge of the last box. A non-*None* total will be passed unchecked
      to the output. In particular this means that right edge of the last
      box may be further to the right than the returned total.

    - 'expand': Distribute the boxes with equal spacing so that the left edge
      of the first box is at 0, and the right edge of the last box is at
      *total*. The parameter *sep* is ignored in this mode. A total of *None*
      is accepted and considered equal to 1. The total is returned unchanged
      (except for the conversion *None* to 1). If the total is smaller than
      the sum of the widths, the laid out boxes will overlap.

    - 'equal': If *total* is given, the total space is divided in N equal
      ranges and each box is left-aligned within its subspace.
      Otherwise (*total* is *None*), *sep* must be provided and each box is
      left-aligned in its subspace of width ``(max(widths) + sep)``. The
      total width is then calculated to be ``N * (max(widths) + sep)``.

    Parameters
    ----------
    wd_list : list of (float, float)
        (width, xdescent) of boxes to be packed.
    total : float or None
        Intended total length. *None* if not used.
    sep : float
        Spacing between boxes.
    mode : {'fixed', 'expand', 'equal'}
        The packing mode.

    Returns
    -------
    total : float
        The total width needed to accommodate the laid out boxes.
    offsets : array of float
        The left offsets of the boxes.

    Align boxes each specified by their ``(height, descent)`` pair.

    For simplicity of the description, the terminology used here assumes a
    horizontal layout (i.e., vertical alignment), but the function works
    equally for a vertical layout.

    Parameters
    ----------
    hd_list
        List of (height, xdescent) of boxes to be aligned.
    height : float or None
        Intended total height. If None, the maximum of the heights in *hd_list*
        is used.
    align : {'baseline', 'left', 'top', 'right', 'bottom', 'center'}
        The alignment anchor of the boxes.

    Returns
    -------
    height
        The total height of the packing (if a value was originally passed in,
        it is returned without checking that it is actually large enough).
    descent
        The descent of the packing.
    offsets
        The bottom offsets of the boxes.

    The OffsetBox is a simple container artist.

    The child artists are meant to be drawn at a relative position to its
    parent.

    Being an artist itself, all parameters are passed on to `.Artist`.

        Delegate the mouse event contains-check to the children.

        As a container, the `.OffsetBox` does not respond itself to
        mouseevents.

        Parameters
        ----------
        mouseevent : `matplotlib.backend_bases.MouseEvent`

        Returns
        -------
        contains : bool
            Whether any values are within the radius.
        details : dict
            An artist-specific dictionary of details of the event context,
            such as which points are contained in the pick radius. See the
            individual Artist subclasses for details.

        Parameters
        ----------
        xy : (float, float) or callable
            The (x, y) coordinates of the offset in display units. These can
            either be given explicitly as a tuple (x, y), or by providing a
            function that converts the extent into the offset. This function
            must have the signature::

        Return the offset as a tuple (x, y).

        The extent parameters have to be provided to handle the case where the
        offset is dynamically determined by a callable (see
        `~.OffsetBox.set_offset`).

        Parameters

            Alignment of boxes.

        mode : {'fixed', 'expand', 'equal'}, default: 'fixed'
            The packing mode.

            - 'fixed' packs the given `.Artist`\s tight with *sep* spacing.
            - 'expand' uses the maximal available space to distribute the
              artists with equal spacing in between.
            - 'equal': Each artist an equal fraction of the available space
              and is left-aligned (or top-aligned) therein.

        children : list of `.Artist`
            The artists to pack.

        Notes
        -----
        *pad* and *sep* are in points and will be scaled with the renderer

        If True, the baseline for multiline text is adjusted so that it is
        (approximately) center-aligned with single-line text.  This is used
        e.g. by the legend implementation so that single-line labels are
        baseline-aligned, but multiline labels are "center"-aligned with them.

S)�AuxTransformBoxaZ
    Offset Box with the aux_transform. Its children will be
    transformed with the aux_transform first then will be
    offsetted. The absolute coordinate of the aux_transform is meaning
    as it will be automatically adjust so that the left-lower corner
    of the bounding box of children will be set to (0, 0) before the
    offset transform.

    It is similar to drawing area, except that the extent of the box
    is not predetermined but calculated from the window extent of its
    children. Furthermore, the extent of the children will be
    calculated in the transformed coordinate.

    An offset box placed according to location *loc*.

    AnchoredOffsetbox has a single child.  When multiple children are needed,
    use an extra OffsetBox to enclose them.  By default, the offset box is
    anchored against its parent axes. You may explicitly specify the
    *bbox_to_anchor*.

            The box location.  Valid locations are
            'upper left', 'upper center', 'upper right',
            'center left', 'center', 'center right',
            'lower left', 'lower center, 'lower right'.
            For backward compatibility, numeric values are accepted as well.
            See the parameter *loc* of `.Legend` for details.
        pad : float, default: 0.4
            Padding around the child as fraction of the fontsize.

        child : `.OffsetBox`
            The box that will be anchored.
        prop : `.FontProperties`
            This is only used as a reference for paddings. If not given,
            :rc:`legend.fontsize` is used.
        frameon : bool
            Whether to draw a frame around the box.
        bbox_to_anchor : `.BboxBase`, 2-tuple, or 4-tuple of floats
            Box that is used to position the legend in conjunction with *loc*.
        bbox_transform : None or :class:`matplotlib.transforms.Transform`
            The transform for the bounding box (*bbox_to_anchor*).
        **kwargs
            All other parameters are passed on to `.OffsetBox`.

DraggableBasea�
    Helper base class for a draggable artist (legend, offsetbox).

    Derived classes must override the following methods::

        def save_offset(self):
            '''
            Called when the object is picked for dragging; should save the
            reference position of the artist.
            '''

        def update_offset(self, dx, dy):
            '''
            Called during the dragging; (*dx*, *dy*) is the pixel offset from
            the point where the mouse drag started.
            '''

    Optionally, you may override the following method::

        def finalize_offset(self):
            '''Called when the mouse is released.'''

    In the current implementation of `.DraggableLegend` and
    `DraggableAnnotation`, `update_offset` places the artists in display
    coordinates, and `finalize_offset` recalculates their position in axes
    coordinate and set a relevant attribute.
