排序和限制要在条形图上显示的条形数量 [英] Sort and limit number of bars to display on bargraph

问题描述

我有一个交通违规数据集，只想在条形图上仅显示每月排名前10的违规.在对值进行排序后是否可以限制小节的数量以仅显示前10个?有42个不同的流量违规列名.

I have a dataset of traffic violations and want to display only the top 10 violations per month on a bargraph. Can I limit the number of bars after sorting values to display only the top 10? There are 42 different column names of traffic violations.

month_jan = df[df.MonthName == "Jan"]
month_jan[feature_cols].sum().sort_values(ascending=0).plot(kind='bar')

Feature_cols是与交通违规相对应的所有42个列名称的列表.

Feature_cols is a list of all 42 column names that correspond to traffic violations.

谢谢！

推荐答案

这将起作用:

month_jan[feature_cols].sum().sort_values(ascending=0)[:10].plot(kind='bar')
