The angle spectrum is one the most used functions in signal processing and Matplotlib has provided a function for plotting Angle Spectrum directly i.e. matplotlib.pyplot.angle_spectrum().

The following are the few examples to illustrate how to use the angle spectrum in matplotlib.

Python code for angle spectrum using matplotlib

import numpy as np
import matplotlib.pyplot as plt

#Example 1
plt.figure()
pts = np.random.rand(30)*.2
pts[[3, 14]] += .8
plt.angle_spectrum(pts)
plt.title('Angle Spectrum Example 1')

#Example 2
plt.figure()
x = np.random.randint(40,80,500)
plt.angle_spectrum(x)
plt.title('Angle Spectrum Example 2')

#Example 3
plt.figure()
x = np.arange(60,150)
plt.angle_spectrum(x, color='purple')
plt.title('Angle Spectrum Example 3')

Output:

Output is as figure
