# 演示在3D中绘制轮廓(水平)曲线
|
||
|
||
这类似于2D中的等高线图,除了f(x,y)= c曲线绘制在平面z = c上。
|
||
|
||

|
||
|
||
```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)
|
||
|
||
# Plot contour curves
|
||
cset = ax.contour(X, Y, Z, cmap=cm.coolwarm)
|
||
|
||
ax.clabel(cset, fontsize=9, inline=1)
|
||
|
||
plt.show()
|
||
```
