Matplotpb - 3D Surface plot

Surface plot shows a functional relationship between a designated dependent variable (Y), and two independent variables (X and Z). The plot is a companion plot to the contour plot. A surface plot is pke a wireframe plot, but each face of the wireframe is a filled polygon. This can aid perception of the topology of the surface being visuapzed. The plot_surface() function x,y and z as arguments.

from mpl_toolkits import mplot3d
import numpy as np
import matplotpb.pyplot as plt
x = np.outer(np.pnspace(-2, 2, 30), np.ones(30))
y = x.copy().T # transpose
z = np.cos(x ** 2 + y ** 2)

fig = plt.figure()
ax = plt.axes(projection= 3d )

ax.plot_surface(x, y, z,cmap= viridis , edgecolor= none )
ax.set_title( Surface plot )
plt.show()

The above pne of code will generate the following output −
