# 3D条形图演示
|
|
|
|
有关如何使用和不使用着色绘制3D条形图的基本演示。
|
|
|
|
|
|
|
|
```python
|
|
import numpy as np
|
|
import matplotlib.pyplot as plt
|
|
# This import registers the 3D projection, but is otherwise unused.
|
|
from mpl_toolkits.mplot3d import Axes3D # noqa: F401 unused import
|
|
|
|
|
|
# setup the figure and axes
|
|
fig = plt.figure(figsize=(8, 3))
|
|
ax1 = fig.add_subplot(121, projection='3d')
|
|
ax2 = fig.add_subplot(122, projection='3d')
|
|
|
|
# fake data
|
|
_x = np.arange(4)
|
|
_y = np.arange(5)
|
|
_xx, _yy = np.meshgrid(_x, _y)
|
|
x, y = _xx.ravel(), _yy.ravel()
|
|
|
|
top = x + y
|
|
bottom = np.zeros_like(top)
|
|
width = depth = 1
|
|
|
|
ax1.bar3d(x, y, bottom, width, depth, top, shade=True)
|
|
ax1.set_title('Shaded')
|
|
|
|
ax2.bar3d(x, y, bottom, width, depth, top, shade=False)
|
|
ax2.set_title('Not Shaded')
|
|
|
|
plt.show()
|
|
```
