matplotlib.pyplot.thetagrids

matplotlib.pyplot.thetagrids(*args, **kwargs) [source]

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, labels : list of lines.Line2D, list of text.Text lines are the theta gridlines and labels are 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') )
