在子图中绘制网格 Python matplotlib [英] Plotting grids across the subplots Python matplotlib

问题描述

我尝试了以下方法:

d = [1,2,3,4,5,6,7,8,9]
f = [0,1,0,0,1,0,1,1,0]
fig = plt.figure()
fig.set_size_inches(30,10)
ax1 = fig.add_subplot(211)
line1 = ax1.plot(d,marker='.',color='b',label="1 row")
ax2 = fig.add_subplot(212)
line1 = ax2.plot(f,marker='.',color='b',label="1 row")
ax1.grid()
ax2.grid()
plt.show()

我得到以下输出:

但是我期待以下输出:

But I was expecting the following output:

如何获取两个图的网格?

How I can get the grids across the two plots?

推荐答案

没有用于创建子图间网格的内置选项.在这种情况下，我想说一个简单的选择是在背景中创建第三个轴，并在x方向上使用相同的网格，以便可以在两个子图之间看到网格线.

There is no built-in option to create inter-subplot grids. In this case I'd say an easy option is to create a third axes in the background with the same grid in x direction, such that the gridline can be seen in between the two subplots.

import matplotlib.pyplot as plt

d = [1,2,3,4,5,6,7,8,9]
f = [0,1,0,0,1,0,1,1,0]

fig, (ax1,ax2) = plt.subplots(nrows=2, sharex=True)
ax3 = fig.add_subplot(111, zorder=-1)
for _, spine in ax3.spines.items():
    spine.set_visible(False)
ax3.tick_params(labelleft=False, labelbottom=False, left=False, right=False )
ax3.get_shared_x_axes().join(ax3,ax1)
ax3.grid(axis="x")


line1 = ax1.plot(d, marker='.', color='b', label="1 row")
line1 = ax2.plot(f, marker='.', color='b', label="1 row")
ax1.grid()
ax2.grid()
plt.show()
