matplotlib.pyplot.rgrids

matplotlib.pyplot.rgrids(radii=None, labels=None, angle=None, fmt=None, **kwargs)

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

Call signatures:

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

When called with no arguments, rgrids simply returns the tuple (lines, labels). When called with arguments, the labels will appear at the specified radial distances and angle.

Parameters:

radiituple with floats

The radii for the radial gridlines

labelstuple with strings or None

The labels to use at each radial gridline. The matplotlib.ticker.ScalarFormatter will be used if None.

anglefloat

The angular position of the radius labels in degrees.

fmtstr or None

Format string used in matplotlib.ticker.FormatStrFormatter. For example '%f'.

Returns:

lineslist of lines.Line2D

The radial gridlines.

labelslist of text.Text

The tick labels.

Other Parameters:

**kwargs

kwargs are optional Text properties for the labels.

Examples

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

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