How to plot a 3D continuous line in Matplotlib?

To plot a 3D continuous line in Matplotlib, we can take the following steps −

  • Set the figure size and adjust the padding between and around the subplots.

  • Create x and y data points using numpy.

  • Create z data points using x and y data points.

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

  • Add an axes as a subplot arrangement with 3D projection.

  • Plot x, y and z data points using plot() method.

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


import numpy as np
from matplotlib import pyplot as plt
plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True
x = np.linspace(-4 * np.pi, 4 * np.pi, 50)
y = np.linspace(-4 * np.pi, 4 * np.pi, 50)
z = x ** 2 + y ** 2
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
ax.plot(x, y, z)
