您可以直接调整 the matplotlib example 在 x 轴上的中断:

y = np.sin(x)

ax.plot(x, y)
ax2.plot(x, y)
ax.set_xlim(0,7.5)
ax2.set_xlim(40,42.5)
# hide the spines between ax and ax2

ax2.yaxis.tick_right()
# This looks pretty good, and was fairly painless, but you can get that
# cut-out diagonal lines look with just a bit more work. The important
# thing to know here is that in axes coordinates, which are always
# between 0-1, spine endpoints are at these locations (0,0), (0,1),
# (1,0), and (1,1). Thus, we just need to put the diagonals in the
# appropriate corners of each of our axes, and so long as we use the
# right transform and disable clipping.
d = .015 # how big to make the diagonal lines in axes coordinates
# arguments to pass plot, just so we don't keep repeating them
kwargs = dict(transform=ax.transAxes, color='k', clip_on=False)
ax.plot((1-d,1+d), (-d,+d), **kwargs)
ax.plot((1-d,1+d),(1-d,1+d), **kwargs)
kwargs.update(transform=ax2.transAxes) # switch to the bottom axes
ax2.plot((-d,+d), (1-d,1+d), **kwargs)
ax2.plot((-d,+d), (-d,+d), **kwargs)
# What's cool about this is that now if we vary the distance between
# ax and ax2 via f.subplots_adjust(hspace=...) or plt.subplot_tool(),
# the diagonal lines will move accordingly, and stay right at the tips
# of the spines they are 'breaking'
plt.show()
出于您的目的,只需绘制两次数据(在每个轴上一次,ax 和 ax2 并适当设置您的 xlims。“中断线”应该移动以匹配新中断,因为它们已绘制在相对轴坐标而不是数据坐标中。
折线只是在一对点之间绘制的未剪裁的绘图线。例如。 ax.plot((1-d,1+d), (-d,+d), **kwargs) 在第一个轴上绘制点 (1-d,-d) 和 (1+d,+d) 之间的断线:这是右下角。如果要更改梯度,请适当更改这些值。例如,要使这个更陡峭,请尝试ax.plot((1-d/2,1+d/2), (-d,+d), **kwargs)
