How to make a quiver plot in polar coordinates using Matplotlib?
To make a quiver plot in polar coordinates using Matplotlib, we can take the following steps −
Set the figure size and adjust the padding between and around the subplots.
Create radii, thetas, theta and r data points using numpy.
Create a new figure or activate an existing figure.
Add an 'ax' to the figure as part of a subplot arrangement.
Make poly collections of arrows.
To display the figure, use show() method.
Example
import numpy as np from matplotlib import pyplot as plt plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True radii = np.linspace(0, 1, 5) thetas = np.linspace(0, 2 * np.pi, 20) theta, r = np.meshgrid(thetas, radii) f = plt.figure() ax = f.add_subplot(polar=True) ax.quiver(theta, r, np.cos(theta) - np.sin(theta), np.sin(theta) + np.cos(theta)) plt.show()
