matplotlib用于绘制折线图和柱状图在一起

    import seaborn as sns
    import matplotlib.pyplot as plt
    
    plt.rcParams['font.sans-serif'] = ['SimHei']  # 中文字体设置-黑体
    plt.rcParams['axes.unicode_minus'] = False  # 解决保存图像是负号'-'显示为方块的问题
    sns.set(font='SimHei', style='white', )  # 解决Seaborn中文显示问题
    
    Income=[2456,2032,1900,2450,2890,2280] # 销售收入
    Profit_Margin=[0.125,0.113,0.102,0.145,0.143,0.151]  #边际利润率
    x = [1, 2, 3, 4, 5, 6]
    
    fig = plt.figure(figsize=(12, 8))
    plt.grid(axis="y",linestyle='-.')
    plt.xticks(fontsize=15)
    plt.title('销售收入与边际利润率的对比图',fontsize=20)
    
    # 画柱形图
    ax1 = fig.add_
