要制作堆叠的3d条形图，您可以累积dz值并将其用作下一个条形的基础。这是一个例子：
from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt
import numpy as np
fig = plt.figure()
ax = fig.add_subplot(111, projection = "3d")
ax.set_xlabel("x")
ax.set_ylabel("y")
ax.set_zlabel("z")
ax.set_xlim3d(0,10)
ax.set_ylim3d(0,10)
xpos = [2,5,8,2,5,8,2,5,8]
ypos = [1,1,1,5,5,5,9,9,9]
zpos = np.zeros(9)
dx = np.ones(9)
dy = np.ones(9)
dz = [np.random.random(9) for i in range(4)] # the heights of the 4 bar sets
_zpos = zpos # the starting zpos for each bar
colors = ['r', 'b', 'g', 'y']
for i in range(4):
ax.bar3d(xpos, ypos, _zpos, dx, dy, dz[i], color=colors[i])
_zpos += dz[i] # add the height of each bar to kNow where to start the next
plt.gca().invert_xaxis()
plt.show()
