我有两个选择你可能想看看。
首先,自己设置轴位置和大小:
# your imports and data above
fig = plt.figure()
ax0a = fig.add_axes([0.1, 0.1, 0.8, 0.25])
ax0b = fig.add_axes([0.1, 0.39, 0.8, 0.25], sharex=ax0a)
ax0c = fig.add_axes([0.1, 0.68, 0.8, 0.25], sharex=ax0a)
ax0a.set_xticklabels([])
ax0b.set_xticklabels([])
ax0a.plot(x,y)
nbins = len(ax0a.get_xticklabels())
ax0a.yaxis.set_major_locator(MaxNLocator(nbins=nbins, prune='upper'))
ax0b.plot(x,y)
ax0b.yaxis.set_major_locator(MaxNLocator(nbins=nbins, prune='upper'))
ax0c.plot(x,y)
ax0c.yaxis.set_major_locator(MaxNLocator(nbins=nbins, prune='upper'))
plt.show()
第二个选项是手动调整偏移文本的位置和字体大小:
# your original code minus data and imports
fig = plt.figure()
gs1 = gridspec.GridSpec(3, 3)
gs1.update(left=0.1, right=0.9, bottom=0.5, hspace=0.0)
ax0a = plt.subplot(gs1[0, :])
ax0b = plt.subplot(gs1[1, :])
ax0c = plt.subplot(gs1[2, :])
ax0a.set_xticklabels([])
ax0b.set_xticklabels([])
ax0a.plot(x,y)
nbins = len(ax0a.get_xticklabels())
ax0a.yaxis.set_major_locator(MaxNLocator(nbins=nbins, prune='upper'))
ax0b.plot(x,y)
ax0b.yaxis.set_major_locator(MaxNLocator(nbins=nbins, prune='upper'))
ax0c.plot(x,y)
ax0c.yaxis.set_major_locator(MaxNLocator(nbins=nbins, prune='upper'))
# play around with location and font of offset text here
ax0a.get_yaxis().get_offset_text().set_x(-0.075)
ax0a.get_yaxis().get_offset_text().set_size(10)
ax0b.get_yaxis().get_offset_text().set_x(-0.075)
ax0b.get_yaxis().get_offset_text().set_size(10)
ax0c.get_yaxis().get_offset_text().set_x(-0.075)
ax0c.get_yaxis().get_offset_text().set_size(10)
plt.show()
