在子图中共享时，Matplotlib hist'stepfilled'会导致y轴限制错误

Question

这是一个错误吗？

x = np.array([ 818711.1744542 ,  669773.03634965,  543356.09981887,

因此，如果我执行＆＃39; stepfilled＆＃39;，则x limit设置为[0,30000]

fig, ax = plt.subplots(2, sharey=True)
ax[0].hist(x, bins=50, histtype='stepfilled');
ax[1].hist(x, bins=50, histtype='stepfilled');

但是，如果我使用其他方法，那很好。

fig, ax = plt.subplots(2, sharey=True)
ax[0].hist(x, bins=50, histtype='bar');
ax[1].hist(x, bins=50, histtype='stepfilled');
