hello there，I want to show the blue part of the plane rather than the orange one. In other words, I want the blue part that is over the orange to be shown in the screen. How can I do that?

My code is below:

```
import matplotlib.pyplot as plt
import numpy as np
fig = plt.figure()
axes = plt.axes(projection='3d')
w1 = np.arange(-5,5,0.5)
w2 = np.arange(-5,5,0.5)
w1,w2 = np.meshgrid(w1,w2)
L = w1**2+w2**2 # 函数定义
L3 = 10*w1.T
curve2 = axes.plot_surface(w1,np.zeros_like(w1),L3)
curve2.set_zorder(3)
curve1 = axes.plot_surface(w1,w2,L) # 画函数
curve1.set_zorder(2)
axes.contour(w1,w2,L, zdim='z',offset=-40,cmap='rainbow') # 画等高线
```
