matplotlib.pyplot.rgrids

matplotlib.pyplot.rgrids(*args, **kwargs)

Get or set the radial gridlines on a polar plot.

call signatures:

lines, labels = rgrids()
lines, labels = rgrids(radii, labels=None, angle=22.5, **kwargs)

When called with no arguments, rgrid() simply returns the tuple (lines, labels), where lines is an array of radial gridlines (Line2D instances) and labels is an array of tick labels (Text instances). When called with arguments, the labels will appear at the specified radial distances and angles.

labels, if not None, is a len(radii) list of strings of the labels to use at each angle.

If labels is None, the rformatter will be used

Examples:

# set the locations of the radial gridlines and labels
lines, labels = rgrids( (0.25, 0.5, 1.0) )

# set the locations and labels of the radial gridlines and labels
lines, labels = rgrids( (0.25, 0.5, 1.0), ('Tom', 'Dick', 'Harry' )
