您可以在三维条形图中设置bottom
,与二维相同:
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')
colors = ['r', 'g', 'b', 'y']
for i, (c, z) in enumerate(zip(colors, [30, 20, 10, 0])):
xs = np.arange(20)
ys = np.random.rand(20)
ys2 = np.random.rand(20)
ys3 = np.random.rand(20)
# You can provide either a single color or an array. To demonstrate this,
# the first bar of each set will be colored cyan.
cs = [c] * len(xs)
cs[0] = 'c'
ax.bar(xs, ys, zs=z, zdir='y', color=cs, alpha=0.8)
ax.bar(xs, ys2, bottom=ys, zs=z, zdir='y', color=colors[(i+1)%4], alpha=0.8)
ax.bar(xs, ys3, bottom=ys+ys2, zs=z, zdir='y', color=colors[(i+2)%4], alpha=0.8)
ax.set_xlabel('X')
ax.set_ylabel('Y')
ax.set_zlabel('Z')
plt.show()

您也可以使用bar3d:zpos参数允许您设置条形图的底部。这里有一个基于matplotlib示例(hist3d_demo.py)
