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:	anglestuple with floats, degrees The angles of the theta gridlines. labelstuple with strings or None The labels to use at each radial gridline. The projections.polar.ThetaFormatter will be used if None. fmtstr or None Format string used in matplotlib.ticker.FormatStrFormatter. For example '%f'. Note that the angle in radians will be used.
Returns:	lines, labelslist 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'))
