按工作日分组并绘制图形熊猫

Question

df1=df.groupby(['usertype','day']).size().reset_index(name='times')

如何按组日和用户类型绘制条形图。

Answer 1

我想你想要这个：

days = ["Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"]
>>> df.pivot(index="day", columns="usertype", values="times").reindex(days).plot.bar()
