1）直方图

# 需求：电影时长分布状况
    # 1、准备数据
    time = [131,  98, 125, 131, 124, 139, 131, 117, 128, 108, 135, 138, 131, 102, 107, 114, 119, 128, 121, 142, 127, 130, 124, 101, 110, 116, 117, 110, 128, 128, 115,  99, 136, 126, 134,  95, 138, 117, 111,78, 132, 124, 113, 150, 110, 117,  86,  95, 144, 105, 126, 130,126, 130, 126, 116, 123, 106, 112, 138, 123,  86, 101,  99, 136,123, 117, 119, 105, 137, 123, 128, 125, 104, 109, 134, 125, 127,105, 120, 107, 129, 116, 108, 132, 103, 136, 118, 102, 120, 114,105, 115, 132, 145, 119, 121, 112, 139, 125, 138, 109, 132, 134,156, 106, 117, 127, 144, 139, 139, 119, 140,  83, 110, 102,123,107, 143, 115, 136, 118, 139, 123, 112, 118, 125, 109, 119, 133,112, 114, 122, 109, 106, 123, 116, 131, 127, 115, 118, 112, 135,115, 146, 137, 116, 103, 144,  83, 123, 111, 110, 111, 100, 154,136, 100, 118, 119, 133, 134, 106, 129, 126, 110, 111, 109, 141,120, 117, 106, 149, 122, 122, 110, 118, 127, 121, 114, 125, 126,114, 140, 103, 130, 141, 117, 106, 114, 121, 114, 133, 137,  92,121, 112, 146,  97, 137, 105,  98, 117, 112,  81,  97, 139, 113,134, 106, 144, 110, 137, 137, 111, 104, 117, 100, 111, 101, 110,105, 129, 137, 112, 120, 113, 133, 112,  83,  94, 146, 133, 101,131, 116, 111,  84, 137, 115, 122, 106, 144, 109, 123, 116, 111,111, 133, 150]
    
    # 2、创建画布
    plt.figure(figsize=(20, 8), dpi=80)
    
    # 3、绘制直方图
    distance = 2
    group_num = int((max(time) - min(time)) / distance)
    
    plt.hist(time, bins=group_num, density=True)
    
    # 修改x轴刻度
    plt.xticks(range(min(time), max(time) + 2, distance))
    
    # 添加网格
    plt.grid(linestyle="--", alpha=0.5)
    
    # 4、显示图像
    plt.show()

2）饼图绘制

# 1、准备数据
    movie_name = ['雷神3：诸神黄昏','正义联盟','东方快车谋杀案','寻梦环游记','全球风暴','降魔传','追捕','七十七天','密战','狂兽','其它']
    
    place_count = [60605,54546,45819,28243,13270,9945,7679,6799,6101,4621,20105]
    
    # 2、创建画布
    plt.figure(figsize=(20, 8), dpi=80)
    #  notebook 里，要设置下面两行才能显示中文
    plt.rcParams['font.family'] = ['SimHei']
    # PyCharm只要下面一行，
    #plt.rcParams['font.sans-serif'] = ['SimHei']
    # 3、绘制饼图
    plt.pie(place_count, labels=movie_name, colors=['b','r','g','y','c','m','y','k','c','g','y'], autopct="%1.2f%%")
    
    # 显示图例
    plt.legend()
    
    plt.axis('equal')
    
    # 4、显示图像
    plt.show()
