对齐标签

使用 Figure.align_xlabels 和 Figure.align_ylabels 对齐xlabel和ylabel

Figure.align_labels 包装了这两个函数。

注意，xlabel “XLabel11” 通常更接近x轴，“YLabel1 0” 将更接近其各自轴的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:
        for tick in ax.get_xticklabels():
            tick.set_rotation(55)
fig.align_labels()  # same as fig.align_xlabels(); fig.align_ylabels()

plt.show()
