Decorator for Artist.draw method. Provides routines
that run before and after the draw call. The before and after functions
are useful for changing artist-dependent renderer attributes or making
other setup function calls, such as starting and flushing a mixed-mode
renderer.

Remove the artist from the figure if possible.
The effect will not be visible until the figure is redrawn, e.g.,
with `.FigureCanvasBase.draw_idle`. Call `~.axes.Axes.relim` to
update the axes limits if desired.
Note: `~.axes.Axes.relim` will not see collections even if the
collection was added to the axes with *autolim* = True.
Note: there is no support for removing the artist's legend entry.

Get the axes bounding box in display space.
The bounding box' width and height are nonnegative.
Subclasses should override for inclusion in the bounding box
"tight" calculation. Default is to return an empty bounding
box at 0, 0.
Be careful when using this function, the results will not update
if the artist window extent of the artist changes. The extent
can change due to any changes in the transform stack, such as
changing the axes limits, the figure size, or the canvas used
(as is done when saving a figure). This can lead to unexpected
behavior where interactive figures will look fine on the screen,
but will save incorrectly.

Parameters
----------
picker : callable
A custom picker function to evaluate if an event is within the
artist. The function must have the signature::
def contains(artist: Artist, event: MouseEvent) -> bool, dict
that returns:
- a bool indicating if the event is within the artist
- a dict of additional information. The dict should at least
return the same information as the default ``contains()``
implementation of the respective artist, but may provide
additional information.

z Artist.pickcCs
||_dS)a=
Define the picking behavior of the artist.
Parameters
----------
picker : None or bool or float or callable
This can be one of the following:
- *None*: Picking is disabled for this artist (default).
- A boolean: If *True* then picking will be enabled and the
artist will fire a pick event if the mouse event is over
the artist.
- A float: If picker is a number it is interpreted as an
epsilon tolerance in points and the artist will fire
off an event if it's data is within epsilon of the mouse
event. For some artists like lines and patch collections,
the artist may provide additional data to the pick event
that is generated, e.g., the indices of the data within
epsilon of the pick event
- A function: If picker is callable, it is a user supplied
function which determines whether the artist is hit by the
mouse event::
hit, props = picker(artist, mouseevent)
to determine the hit test. if the mouse event is over the
artist, return *hit=True* and props is a dictionary of
properties you want added to the PickEvent attributes.

Returns the snap setting.
See `.set_snap` for details.
z path.snapFN)r rA)rrrr<00>get_snap9szArtist.get_snapcCs||_d|_dS)a<>
Set the snapping behavior.
Snapping aligns positions with the pixel grid, which results in
clearer images. For example, if a black line of 1px width was
defined at a position in between two pixels, the resulting image
would contain the interpolated value of that line in the pixel grid,
which would be a grey value on both adjacent pixel positions. In
contrast, snapping will move the line to the nearest integer pixel
value, so that the resulting image will really contain a 1px wide
black line.
Snapping is currently only supported by the Agg and MacOSX backends.
Parameters
----------
snap : bool or None
Possible values:
- *True*: Snap vertices to the nearest pixel center.
- *False*: Do not modify vertex positions.
- *None*: (auto) If the path contains only rectilinear line
segments, round to the nearest pixel center.

Returns
-------

A 3-tuple with the following elements:
- *scale*: The amplitude of the wiggle perpendicular to the
source line.
- *length*: The length of the wiggle along the line.
- *randomness*: The scale factor by which the length is
shrunken or expanded.
Returns *None* if no sketch parameters were set.

:class:`~matplotlib.transforms.Transform` instance, which will be
applied to the path before using it for clipping, must be provided;
or
- ``None``, to remove a previously set clipping path.
For efficiency, if the path happens to be an axis-aligned rectangle,
this method will set the clipping box to the corresponding rectangle
and set the clipping path to ``None``.

``x`` and ``y`` sticky edge lists for autoscaling.
When performing autoscaling, if a data limit coincides with a value in
the corresponding sticky_edges list, then no margin will be added--the
view limit "sticks" to the edge. A typical use case is histograms,
where one usually expects no margin on the bottom edge (0) of the
histogram.
This attribute cannot be assigned to; however, the ``x`` and ``y``
lists can be modified in place as needed.

Find artist objects.
Recursively find all `.Artist` instances contained in the artist.
Parameters
----------
match
A filter criterion for the matches. This can be
- *None*: Return all objects contained in artist.
- A function with signature ``def match(artist: Artist) -> bool``.
The result will only contain artists for which the function
returns *True*.
- A class instance: e.g., `.Line2D`. The result will only contain
artists of this class or its subclasses (``isinstance`` check).
include_self : bool
Include *self* in the list to be checked for a match.

Return the cursor data for a given event.
.. note::
This method is intended to be overridden by artist subclasses.
As an end-user of Matplotlib you will most likely not call this
method yourself.
Cursor data can be used by Artists to provide additional context
information for a given event. The default implementation just returns
*None*.
Subclasses can override the method and return arbitrary data. However,
when doing so, they must ensure that `.format_cursor_data` can convert
the data to a string representation.
The only current use case is displaying the z-value of an `.AxesImage`
in the status bar of a plot window, while moving the mouse.

Return the value of object's property. *property* is an optional string
for the property you want to return
Example usage::
getp(obj) # get all the object properties
getp(obj, 'linestyle') # get the linestyle property
*obj* is a :class:`Artist` instance, e.g.,
:class:`~matplotlib.lines.Line2D` or an instance of a
:class:`~matplotlib.axes.Axes` or :class:`matplotlib.text.Text`.
If the *property* is 'somename', this function returns
obj.get_somename()
:func:`getp` can be used to query all the gettable properties with
``getp(obj)``. Many properties have aliases for shorter typing, e.g.
'lw' is an alias for 'linewidth'. In the output, aliases and full
property names will be listed as:
property or alias = value
e.g.:
linewidth or lw = 2

Set a property on an artist object.
matplotlib supports the use of :func:`setp` ("set property") and
:func:`getp` to set and get object properties, as well as to do
introspection on the object. For example, to set the linestyle of a
line to be dashed, you can do::
>>> line, = plot([1,2,3])
>>> setp(line, linestyle='--')
If you want to know the valid types of arguments, you can provide
the name of the property you want to set without a value::
>>> setp(line, 'linestyle')
linestyle: [ '-' | '--' | '-.' | ':' | 'steps' | 'None' ]
If you want to see all the properties that can be set, and their
possible values, you can do::
>>> setp(line)
... long output listing omitted
You may specify another output file to `setp` if `sys.stdout` is not
acceptable for some reason using the `file` keyword-only argument::
>>> with fopen('output.log') as f:
>>> setp(line, file=f)
:func:`setp` operates on a single instance or a iterable of
instances. If you are in query mode introspecting the possible
values, only the first instance in the sequence is used. When
actually setting values, all the instances will be set. e.g.,
suppose you have a list of two lines, the following will make both
lines thicker and red::
>>> x = arange(0,1.0,0.01)
>>> y1 = sin(2*pi*x)
>>> y2 = sin(4*pi*x)
>>> lines = plot(x, y1, x, y2)
>>> setp(lines, linewidth=2, color='r')
:func:`setp` works with the MATLAB style string/value pairs or
with python kwargs. For example, the following are equivalent::
>>> setp(lines, 'linewidth', 2, 'color', 'r') # MATLAB style
>>> setp(lines, linewidth=2, color='r') # python style
