对齐标签

Figure.align_xlabels使用and 对齐 xlabel 和 ylabelFigure.align_ylabels

Figure.align_labels包装了这两个函数。

请注意，xlabel "XLabel1 1" 通常会更靠近 x 轴，而 "YLabel1 0" 会更靠近各自轴的 y 轴。

import matplotlib.pyplot as plt
import numpy as np
import matplotlib.gridspec as gridspec

fig = plt.figure(tight_layout=True)
gs = gridspec.GridSpec(2, 2)

ax = fig.add_subplot(gs[0, :])
ax.plot(np.arange(0, 1e6, 1000))
ax.set_ylabel('YLabel0')
ax.set_xlabel('XLabel0')

for i in range(2):
    ax = fig.add_subplot(gs[1, i])
    ax.plot(np.arange(1., 0., -0.1) * 2000., np.arange(1., 0., -0.1))
    ax.set_ylabel('YLabel1 %d' % i)
    ax.set_xlabel('XLabel1 %d' % i)
    if i == 0:
        ax.tick_params(axis='x', rotation=55)
fig.align_labels()  # same as fig.align_xlabels(); fig.align_ylabels()

plt.show()
