Fonction quiverkey - module matplotlib.pyplot

Signature de la fonction quiverkey

def quiverkey(Q: 'Quiver', X: 'float', Y: 'float', U: 'float', label: 'str', **kwargs) -> 'QuiverKey' 

Description

help(matplotlib.pyplot.quiverkey)

Add a key to a quiver plot.

The positioning of the key depends on *X*, *Y*, *coordinates*, and
*labelpos*.  If *labelpos* is 'N' or 'S', *X*, *Y* give the position of
the middle of the key arrow.  If *labelpos* is 'E', *X*, *Y* positions
the head, and if *labelpos* is 'W', *X*, *Y* positions the tail; in
either of these two cases, *X*, *Y* is somewhere in the middle of the
arrow+label key object.

Parameters
----------
Q : `~matplotlib.quiver.Quiver`
    A `.Quiver` object as returned by a call to `~.Axes.quiver()`.
X, Y : float
    The location of the key.
U : float
    The length of the key.
label : str
    The key label (e.g., length and units of the key).
angle : float, default: 0
    The angle of the key arrow, in degrees anti-clockwise from the
    horizontal axis.
coordinates : {'axes', 'figure', 'data', 'inches'}, default: 'axes'
    Coordinate system and units for *X*, *Y*: 'axes' and 'figure' are
    normalized coordinate systems with (0, 0) in the lower left and
    (1, 1) in the upper right; 'data' are the axes data coordinates
    (used for the locations of the vectors in the quiver plot itself);
    'inches' is position in the figure in inches, with (0, 0) at the
    lower left corner.
color : :mpltype:`color`
    Overrides face and edge colors from *Q*.
labelpos : {'N', 'S', 'E', 'W'}
    Position the label above, below, to the right, to the left of the
    arrow, respectively.
labelsep : float, default: 0.1
    Distance in inches between the arrow and the label.
labelcolor : :mpltype:`color`, default: :rc:`text.color`
    Label color.
fontproperties : dict, optional
    A dictionary with keyword arguments accepted by the
    `~matplotlib.font_manager.FontProperties` initializer:
    *family*, *style*, *variant*, *size*, *weight*.
zorder : float
    The zorder of the key. The default is 0.1 above *Q*.
**kwargs
    Any additional keyword arguments are used to override vector
    properties taken from *Q*.

Notes
-----

.. note::

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