How can set the horizontal gridlines based on the right y-axis with matplotlib?
问题
我们可以使用Matlab来基于右Y轴设置网格：
您可以看到水平网格线是基于右Y轴而不是左Y轴的。在Matplotlib中，ax.grid(axis="y")会绘制基于左Y轴的水平网格线。
那么，如何在Matplotlib中实现呢？

You see that the horizontal gridlines based on the right y-axis ,instead of the left y-axis.In matplotlib,ax.grid(axis = "y") draw the horizontal gridlines based on the left y-axis.
ax.grid(axis = "y")
How can do it with matplotlib then?

由于您有两个y轴，您可以使用ax2.grid()来设置次要轴的网格为真。示例代码如下：
fig, ax=plt.subplots(figsize=(7,7))
ax1=ax.twinx()
ax1.set_ylim(-1,3)
ax1.grid()
ax.xaxis.grid(True)
plt.show()
英文:
As you have two y-axis, you can set the secondary axis grid to true using ax2.grid(). Working example...
fig, ax=plt.subplots(figsize=(7,7))
ax1=ax.twinx()
ax1.set_ylim(-1,3)
ax1.grid()
ax.xaxis.grid(True)
plt.show()
