Filled contoursΒΆ

contourf differs from contour in that it creates filled contours, ie. a discrete number of colours are used to shade the domain.

This is like a contourf plot in 2D except that the shaded region corresponding to the level c is graphed on the plane z=c.

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

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

cset = ax.contourf(X, Y, Z, cmap=cm.coolwarm)

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