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

If *prop* is *None*, return a list of strings of all settable properies
and their valid values. Format the output for ReST
If *prop* is not *None*, it is a valid property name and that
property will be returned as a string of property : valid
values.

If *match* is not None, it can be
- function with signature ``boolean = match(artist)``
- class instance: eg :class:`~matplotlib.lines.Line2D`
used to filter matches.

Return the value of handle property. property is an optional string
for the property you want to return
Example usage::
getp(o) # get all the object properties
getp(o, 'linestyle') # get the linestyle property
*o* is a :class:`Artist` instance, eg
:class:`~matplotllib.lines.Line2D` or an instance of a
:class:`~matplotlib.axes.Axes` or :class:`matplotlib.text.Text`.
If the *property* is 'somename', this function returns
o.get_somename()
:func:`getp` can be used to query all the gettable properties with
``getp(o)``. 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

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
:func:`setp` operates on a single instance or a list 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(TM) 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
