+# 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()
+```
