输入：
dfB=pd.qcut(dfA, 4, labels=quartiles)
输出：

5587 min to 1st quartile
PG 6687 3rd quartile to max
5943 median to 3rd quartile
5987 median to 3rd quartile
PG-13 6380 3rd quartile to max
5954 3rd quartile to max
6624 3rd quartile to max
R 6616 median to 3rd quartile
6184 median to 3rd quartile

我正在尝试创建一个条形图，以可视化每个Label组（G，PG，PG-13，R）的每个四分位数类别的value_count（）。下面的代码生成一个条形图，该条形图仅显示每个四分位数类别的value_count（）。我不确定如何创建将每个Label组都考虑在内的堆叠条形图？
dfB.value_counts().plot.bar()
