Signature de la méthode add_subplot

def add_subplot(self, *args, **kwargs) 

Description

add_subplot.__doc__

Add an `~.axes.Axes` to the figure as part of a subplot arrangement.

Call signatures::

   add_subplot(nrows, ncols, index, **kwargs)
   add_subplot(pos, **kwargs)
   add_subplot(ax)
   add_subplot()

Parameters
----------
*args : int, (int, int, *index*), or `.SubplotSpec`, default: (1, 1, 1)
    The position of the subplot described by one of

    - Three integers (*nrows*, *ncols*, *index*). The subplot will
      take the *index* position on a grid with *nrows* rows and
      *ncols* columns. *index* starts at 1 in the upper left corner
      and increases to the right.  *index* can also be a two-tuple
      specifying the (*first*, *last*) indices (1-based, and including
      *last*) of the subplot, e.g., ``fig.add_subplot(3, 1, (1, 2))``
      makes a subplot that spans the upper 2/3 of the figure.
    - A 3-digit integer. The digits are interpreted as if given
      separately as three single-digit integers, i.e.
      ``fig.add_subplot(235)`` is the same as
      ``fig.add_subplot(2, 3, 5)``. Note that this can only be used
      if there are no more than 9 subplots.
    - A `.SubplotSpec`.

    In rare circumstances, `.add_subplot` may be called with a single
    argument, a subplot Axes instance already created in the
    present figure but not in the figure's list of Axes.

projection : {None, 'aitoff', 'hammer', 'lambert', 'mollweide', 'polar', 'rectilinear', str}, optional
    The projection type of the subplot (`~.axes.Axes`). *str* is the
    name of a custom projection, see `~matplotlib.projections`. The
    default None results in a 'rectilinear' projection.

polar : bool, default: False
    If True, equivalent to projection='polar'.

axes_class : subclass type of `~.axes.Axes`, optional
    The `.axes.Axes` subclass that is instantiated.  This parameter
    is incompatible with *projection* and *polar*.  See
    :ref:`axisartist_users-guide-index` for examples.

sharex, sharey : `~.axes.Axes`, optional
    Share the x or y `~matplotlib.axis` with sharex and/or sharey.
    The axis will have the same limits, ticks, and scale as the axis
    of the shared axes.

label : str
    A label for the returned Axes.

Returns
-------
`.axes.SubplotBase`, or another subclass of `~.axes.Axes`

    The Axes of the subplot. The returned Axes base class depends on
    the projection used. It is `~.axes.Axes` if rectilinear projection
    is used and `.projections.polar.PolarAxes` if polar projection
    is used. The returned Axes is then a subplot subclass of the
    base class.

Other Parameters
----------------
**kwargs
    This method also takes the keyword arguments for the returned Axes
    base class; except for the *figure* argument. The keyword arguments
    for the rectilinear base class `~.axes.Axes` can be found in
    the following table but there might also be other keyword
    arguments if another projection is used.

Examples

::

    fig = plt.figure()

    fig.add_subplot(231)
    ax1 = fig.add_subplot(2, 3, 1)  # equivalent but more general

    fig.add_subplot(232, frameon=False)  # subplot with no frame
    fig.add_subplot(233, projection='polar')  # polar subplot
    fig.add_subplot(234, sharex=ax1)  # subplot sharing x-axis with ax1
    fig.add_subplot(235, facecolor="red")  # red subplot

    ax1.remove()  # delete ax1 from the figure
    fig.add_subplot(ax1)  # add ax1 back to the figure
