Description
Bug summary
Using the example from the matplotlib website for making a 3D surface colormap plot gives a deprecation warning.
Code for reproduction
import matplotlib.pyplot as plt
import numpy as np
from matplotlib import cm
from matplotlib.ticker import LinearLocator
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)
ax.zaxis.set_major_locator(LinearLocator(10))
# A StrMethodFormatter is used automatically
ax.zaxis.set_major_formatter('{x:.02f}')
# Add a color bar which maps values to colors.
fig.colorbar(surf, shrink=0.5, aspect=5)
plt.show()Actual outcome
MatplotlibDeprecationWarning: The clean function was deprecated in Matplotlib 3.8 and will be removed two minor releases later. Use none, you no longer need to clean a Grouper instead.
surf = ax.plot_surface(X, Y, Z, cmap=cm.coolwarm,
Expected outcome
The expected plot is there, I but would not expect any warning.
