下面我正在分享我的数据框，我正在尝试获取一个按集群分隔的 Count x Name 直方图，但没有成功。

我正在尝试按集群对每个“名称”的体积进行分组，但我的 Y 轴显示为 1，我想绘制计数 x 名称。我应该如何更改我的直方图调用？

df_result2.hist(column='Name', by='cluster', bins=10, grid=True, figsize=(20,10))

【解决方案1】：

你需要绘制条形图而不是直方图

new_df.groupby('cluster').plot(x="Name", y=["Count"], kind="bar", grid=True, figsize=(20,10), ylim=(0,2500000.0))
