3D surface (colormap)#

Demonstrates plotting a 3D surface colored with the coolwarm colormap. The surface is made opaque by using antialiased=False.

Also demonstrates using the LinearLocator and custom formatting for the z axis tick labels.

import matplotlib.pyplot as plt
from matplotlib import cm
from matplotlib.ticker import LinearLocator
import numpy as np

fig, ax = plt.subplots(subplot_kw={"projection": "3d"})

# Make data.
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)

# Plot the surface.
surf = ax.plot_surface(X, Y, Z, cmap=cm.coolwarm,
                       linewidth=0, antialiased=False)

# Customize the z axis.
ax.set_zlim(-1.01, 1.01)
# A StrMethodFormatter is used automatically

# Add a color bar which maps values to colors.
fig.colorbar(surf, shrink=0.5, aspect=5)
