matplotlib.pyplot.thetagrids

matplotlib.pyplot. thetagrids ( angles=None, labels=None, fmt=None, **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 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'))
