Python+Pyecharts：快速构建各种数据可视化图表❥满足你的一切常用需求❥

Python+Pyecharts：快速构建各种数据可视化图表❥满足你的一切常用需求❥

做一个写出‘有用’代码的人！Echarts 是原百度出品，现已移交Apache开源组织管理，使得其更加强大，那么怎么用呢，下面就用一下最常用的几个图表，几行代码就可以，看就完事了！

首先安装模块：pip install pyecharts ，由于生成的是html页面，所以我在这里引入了一个html转图片的工具imgkit,先下载exe程序，再安装模块：pip install imgkit，如果不需要转图片，可以忽略！

这里使用的是pyecharts自带的演示数据集Faker，choose()随机生成一个列表，列表里的是同一类事务，values()生成一个默认20,150之间随机数的一个列表，列表长度均为7！

常用11个

• 1.直方图
• 2.折线图
• 3.饼图
• 4.漏斗图
• 5.仪表盘图
• 6.联动图
• 7.水球图
• 8.分栏显示图
• 9.表格图
• 10.时间线图
• 11.词云图
• 12.完整代码

各个模块，在这里先导入，下面是各个函数，最后main方法调用，生成各种图表

    data = data1 + data2
    wordcloud = (
        WordCloud()
            .add(series_name='销量分析', data_pair=data, word_size_range=[20, 150])
