How to surface plot/3D plot from a dataframe (Matplotlib)?

To surface plot/3d, we would require 2D data points, not 1D dataframe.


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

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

  • Add an '~.axes.Axes' to the figure as part of a subplot arrangement using add_subplot() method.

  • Initialize a variable 'n' for the number of samples.

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

  • Use plot_surface() method to make surface 3d.

  • 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

fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')

n = 50
x = np.random.rand(n)
y = np.tan(x)
z = np.random.rand(n, n)

surf = ax.plot_surface(y, x, z, rstride=1, cstride=1, cmap='copper',linewidth=0, antialiased=False)
