The surface is made opaque by using antialiased=False. Also demonstrates using the LinearLocator and custom formatting for the z axis tick labels. .. image:: /gallery/mplot3d/images/sphx_glr_surface3d_001.png :class: sphx-glr-single-img .. code-block:: default import matplotlib.pyplot as plt from matplotlib import cm from matplotlib.ticker import LinearLocator, FormatStrFormatter import numpy as np fig = plt.figure() ax = fig.gca(projection='3d') # Make data.
