Matplotlib is a library in Python and it is numerical – mathematical extension for NumPy library. Pyplot is a state-based interface to a Matplotlib module which provides a MATLAB-like interface.
matplotlib.pyplot.polar() Function:
The polar() function in pyplot module of matplotlib library is used to make a polar plot.
Syntax: matplotlib.pyplot.polar(*args, **kwargs)
Parameters: This method does not accept any parameters.
Returns: This method does not returns any value.
Below examples illustrate the matplotlib.pyplot.polar() function in matplotlib.pyplot:
Example #1:
# Implementation of matplotlib function import matplotlib.pyplot as plt import matplotlib.transforms as mtransforms import numpy as np from matplotlib.transforms import offset_copy xs = np.arange(-2, 2) ys = np.cos(xs**2) plt.polar(xs, ys) plt.title('matplotlib.pyplot.polar() function Example', fontweight ="bold") plt.show() |
Output:
Example #2:
# Implementation of matplotlib function import matplotlib.pyplot as plt import matplotlib.transforms as mtransforms import numpy as np from matplotlib.transforms import offset_copy xs = np.arange(8) ys = np.cos(xs**2) fig = plt.figure(figsize =(5, 10)) ax = plt.subplot(1, 1, 1) trans_offset = mtransforms.offset_copy(ax.transData, fig = fig, y = 6, units ='dots') for x, y in zip(xs, ys): plt.polar(x, y, 'go') plt.text(x, y, '% d, % d' % (int(x), int(y)), transform = trans_offset, horizontalalignment ='center', verticalalignment ='bottom') plt.title('matplotlib.pyplot.polar() function Example', fontweight ="bold") plt.show() |
Output:
