使用pyecharts繪製條形圖

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
from pyecharts import Line

data  = pd.read_csv('data_clean.csv') #讀取data_clean數據
data['time'] = pd.to_datetime(data['time']) #通過pd.to_datetime將該列數據轉換爲時間類型
AQI_total_mean = data[data['time']<=pd.to_datetime('2019-02-06 23:59:59')].groupby(['time'])['AQI'].mean()          def city_AQI(data, cities):
    line = Line("春節期間空氣質量指數", "2019年除夕到初二", width=800)
    for city in cities:
        city_aqi = data[(data['city']==city)&(data['time']<=pd.to_datetime('2019-02-06 23:59:59'))]
        line.add(city, city_aqi.index, np.round(city_aqi['AQI'].values,0), is_smooth=True,
             legend_text_size=18,xaxis_label_textsize=14,yaxis_label_textsize=18,
             xaxis_rotate=20, yaxis_min=8, mark_point=["max"])
    return line.render()
print(city_AQI(data=data,cities=['北京市', '天津市']))
