python - 如何使用for循环将每个轴绘制在另一个轴之上

Question

我正在尝试从 Titanic 数据集中获取可视化：

import seaborn as sns

fig, axs = plt.subplots(nrows=5, ncols=1)
X=['sex', 'cabin', 'port_of_embarkation', 'is_boy', 'is_married_female']

for ax, x in zip(axs, X):
    sns.barplot(x, y='survived', data=main_df, estimator=lambda x: sum(x==1)*100.0/len(x))

where X是分类列的向量，main_df并且survived是二元列。

我们的想法是让这五个图彼此重叠，但是当前输出如下所示：

我在结构中缺少什么？有没有其他图书馆可以完成这项任务？

您忘记为每个图指定轴，因此它将它们全部绘制在同一轴上。

for ax, x in zip(axs, X):
    sns.barplot(ax=ax, x=x, y='survived', data=main_df, estimator=lambda x: sum(x==1)*100.0/len(x))
