# 填充轮廓
contourf与轮廓的不同之处在于它创建了填充轮廓即。 离散数量的颜色用于遮蔽域。
这类似于2D中的等高线图除了对应于等级c的阴影区域在平面z = c上绘制图形。
![填充轮廓示例](https://matplotlib.org/_images/sphx_glr_contourf3d_001.png)
```python
from mpl_toolkits.mplot3d import axes3d
import matplotlib.pyplot as plt
from matplotlib import cm
fig = plt.figure()
ax = fig.gca(projection='3d')
X, Y, Z = axes3d.get_test_data(0.05)
cset = ax.contourf(X, Y, Z, cmap=cm.coolwarm)
ax.clabel(cset, fontsize=9, inline=1)
plt.show()
```
