您可以通过注释条与参考问题类似地执行此操作。对于堆积的条形图，您必须稍微调整标签的位置，以使其位于所需位置。您可以使用horizontalalignment，verticalalignment并像我一样添加一点空白（+.5）。

#used gray colormap, you can use your own colors by replacing colormap='gray' with color=colors
colors = ["#252525", "#636363", "#969696", "#cccccc", "#f7f7f7"]
plt.rcParams['axes.prop_cycle'] = cycler(color=colors)

df[col] = df[col].apply(lambda x:x*100 / df[col].sum())
ax = df.T.plot.barh(stacked=True, colormap='gray', edgecolor='black', linewidth=1)
for lbl in ax.patches:
ax.annotate("{:.0f}%".format(int(lbl.get_width())), (lbl.get_x(), lbl.get_y()+.5), verticalalignment='bottom', horizontalalignment='top', fontsize=8, color='black')
ax.legend(loc='center left', b@R_941_2419@_to_anchor=(1.0, .5))
ax.spines['top'].set_visible(False)
ax.spines['right'].set_visible(False)
ax.spines['bottom'].set_visible(False)
ax.spines['left'].set_visible(False)
plt.show()
