Plotting points on the surface of a sphere in Python's Matplotlib

MatplotlibPythonData Visualization

To plot points on the surface of a sphere in Python, we can use plot_surface() method.


  • Create a new figure or activate an existing figure using figure() method.

  • Add a set of subplots using add_subplot() method with 3d projection.

  • Initialize a variable, r.

  • Get the theta value for spherical points and x, y, and z data points using numpy.

  • Plot the surface using plot_surface() method.

  • To display the figure, use show() method.


import matplotlib.pyplot as plt
import numpy as np
plt.rcParams["figure.figsize"] = [7.00, 3.50]
plt.rcParams["figure.autolayout"] = True
fig = plt.figure()
ax = fig.add_subplot(projection='3d')
r = 0.05
u, v = np.mgrid[0:2 * np.pi:30j, 0:np.pi:20j]
x = np.cos(u) * np.sin(v)
y = np.sin(u) * np.sin(v)
z = np.cos(v)
ax.plot_surface(x, y, z,
