mplot3d example code: contour3d_demo2.py¶

(Source code, png, pdf)

'''
Demonstrates plotting contour (level) curves in 3D using the extend3d option.

This modification of the contour3d_demo example uses extend3d=True to
extend the curves vertically into 'ribbons'.
'''

from mpl_toolkits.mplot3d import axes3d
import matplotlib.pyplot as plt
from matplotlib import cm

fig = plt.figure()
ax = fig.gca(projection='3d')
X, Y, Z = axes3d.get_test_data(0.05)

cset = ax.contour(X, Y, Z, extend3d=True, cmap=cm.coolwarm)

ax.clabel(cset, fontsize=9, inline=1)

plt.show()
