Module « matplotlib.pyplot »

Fonction matshow - module matplotlib.pyplot

Signature de la fonction matshow

def matshow(A: 'ArrayLike', fignum: 'None | int' = None, **kwargs) -> 'AxesImage' 

Description

help(matplotlib.pyplot.matshow)

Display a 2D array as a matrix in a new figure window.

The origin is set at the upper left hand corner.
The indexing is ``(row, column)`` so that the first index runs vertically
and the second index runs horizontally in the figure:

.. code-block:: none

    A[0, 0]   ⋯ A[0, M-1]
       ⋮             ⋮
    A[N-1, 0] ⋯ A[N-1, M-1]

The aspect ratio of the figure window is that of the array,
unless this would make an excessively short or narrow figure.

Tick labels for the xaxis are placed on top.

Parameters
----------
A : 2D array-like
    The matrix to be displayed.

fignum : None or int
    If *None*, create a new, appropriately sized figure window.

    If 0, use the current Axes (creating one if there is none, without ever
    adjusting the figure size).

    Otherwise, create a new Axes on the figure with the given number
    (creating it at the appropriate size if it does not exist, but not
    adjusting the figure size otherwise).  Note that this will be drawn on
    top of any preexisting Axes on the figure.

Returns
-------
`~matplotlib.image.AxesImage`

Other Parameters
----------------
**kwargs : `~matplotlib.axes.Axes.imshow` arguments
