I found the following example (http://matplotlib.sourceforge.net/

examples/mplot3d/subplot3d_demo.html), but it doesn't work.

---

from mpl_toolkits.mplot3d.axes3d import Axes3D

import matplotlib.pyplot as plt

# imports specific to the plots in this example

import numpy as np

from matplotlib import cm

from mpl_toolkits.mplot3d.axes3d import get_test_data

fig = plt.figure(figsize=(9.5,5.0))

#---- First subplot

ax = fig.add_subplot(1, 2, 1, projection='3d')

X = np.arange(-5, 5, 0.25)

Y = np.arange(-5, 5, 0.25)

X, Y = np.meshgrid(X, Y)

R = np.sqrt(X**2 + Y**2)

Z = np.sin(R)

surf = ax.plot_surface(X, Y, Z, rstride=1, cstride=1, cmap=cm.jet,

linewidth=0, antialiased=False)

ax.set_zlim3d(-1.01, 1.01)

fig.colorbar(surf, shrink=0.5, aspect=10)

#---- Second subplot

ax = fig.add_subplot(1, 2, 2, projection='3d')

X, Y, Z = get_test_data(0.05)

ax.plot_wireframe(X, Y, Z, rstride=10, cstride=10)

plt.show()

The error message is:
