Python数据可视化采用Seaborn库（下）

    import pandas as pd
    import numpy as np
    from matplotlib import pyplot as plt, cm
    import seaborn as sns
    from sqlalchemy import create_engine
    import sqlite3
    import warnings
    %matplotlib
    
    warnings.filterwarnings('ignore')
    # plt.style.use('ggplot')
    sns.set()
    np.random.seed(2019)
    # 解决使用seaborn风格中文乱码问题
    sns.set_style('whitegrid',{'font.sans-serif':['simhei']})
    
    # 连接数据库
    engine = create_engine('sqlite:///steam.sqlite')
    
    # 导入数据
    df = pd.read_sql('select * from steam', con=engine)
