Fonction thetagrids - module matplotlib.pyplot

Signature de la fonction thetagrids

def thetagrids(angles: 'ArrayLike | None' = None, labels: 'Sequence[str | Text] | None' = None, fmt: 'str | None' = None, **kwargs) -> 'tuple[list[Line2D], list[Text]]' 

Description

help(matplotlib.pyplot.thetagrids)

Get or set the theta gridlines on the current polar plot.

Call signatures::

 lines, labels = thetagrids()
 lines, labels = thetagrids(angles, labels=None, fmt=None, **kwargs)

When called with no arguments, `.thetagrids` simply returns the tuple
(*lines*, *labels*). When called with arguments, the labels will
appear at the specified angles.

Parameters
----------
angles : tuple with floats, degrees
    The angles of the theta gridlines.

labels : tuple with strings or None
    The labels to use at each radial gridline. The
    `.projections.polar.ThetaFormatter` will be used if None.

fmt : str or None
    Format string used in `matplotlib.ticker.FormatStrFormatter`.
    For example '%f'. Note that the angle in radians will be used.

Returns
-------
lines : list of `.lines.Line2D`
    The theta gridlines.

labels : list of `.text.Text`
    The tick labels.

Other Parameters
----------------
**kwargs
    *kwargs* are optional `.Text` properties for the labels.

Examples
--------
::

  # set the locations of the angular gridlines
  lines, labels = thetagrids(range(45, 360, 90))

  # set the locations and labels of the angular gridlines
  lines, labels = thetagrids(range(45, 360, 90), ('NE', 'NW', 'SW', 'SE'))
