Fonction margins - module matplotlib.pyplot

Signature de la fonction margins

def margins(*margins: 'float', x: 'float | None' = None, y: 'float | None' = None, tight: 'bool | None' = True) -> 'tuple[float, float] | None' 

Description

help(matplotlib.pyplot.margins)

Set or retrieve margins around the data for autoscaling axis limits.

This allows to configure the padding around the data without having to
set explicit limits using `~.Axes.set_xlim` / `~.Axes.set_ylim`.

Autoscaling determines the axis limits by adding *margin* times the
data interval as padding around the data. See the following illustration:

.. plot:: _embedded_plots/axes_margins.py

All input parameters must be floats greater than -0.5. Passing both
positional and keyword arguments is invalid and will raise a TypeError.
If no arguments (positional or otherwise) are provided, the current
margins will remain unchanged and simply be returned.

The default margins are :rc:`axes.xmargin` and :rc:`axes.ymargin`.

Parameters
----------
*margins : float, optional
    If a single positional argument is provided, it specifies
    both margins of the x-axis and y-axis limits. If two
    positional arguments are provided, they will be interpreted
    as *xmargin*, *ymargin*. If setting the margin on a single
    axis is desired, use the keyword arguments described below.

x, y : float, optional
    Specific margin values for the x-axis and y-axis,
    respectively. These cannot be used with positional
    arguments, but can be used individually to alter on e.g.,
    only the y-axis.

tight : bool or None, default: True
    The *tight* parameter is passed to `~.axes.Axes.autoscale_view`,
    which is executed after a margin is changed; the default
    here is *True*, on the assumption that when margins are
    specified, no additional padding to match tick marks is
    usually desired.  Setting *tight* to *None* preserves
    the previous setting.

Returns
-------
xmargin, ymargin : float

Notes
-----

.. note::

    This is the :ref:`pyplot wrapper <pyplot_interface>` for `.axes.Axes.margins`.

If a previously used Axes method such as :meth:`pcolor` has set
`~.Axes.use_sticky_edges` to `True`, only the limits not set by
the "sticky artists" will be modified. To force all
margins to be set, set `~.Axes.use_sticky_edges` to `False`
before calling :meth:`margins`.
