echarts散点图例子scatter-weight折腾记之echarts参数修改

上一篇折腾记地址：https://www.cnblogs.com/qtx-/p/11606541.html

1、修改echarts的markline为虚线；

2、去掉echarts的markline的箭头；

以下代码可实现：

            markLine : {
                symbol:'none',
                lineStyle: {
                    normal: {
                        type: 'dashed'
                    }
                },
                label:{
                    formatter:'采购价格红线值{c}',
                    position:'middle'
                },
                data : [
                    {type : 'average', name: '平均值'}
                ]
            }

完整配置如下：

option = {
    dataset:{
        source:[[61.2,51.6,74,"北京分"],[67.5,59,75.3,"广州分"],[59.5,49.2,9305,"浙江分"],[57,63,8605,"石家庄分"],[55.8,53.6,87.2,"黑龙江分"],[70,59,8105,"河南分"],[59.1,47.6,84,"福建分"],[66,69.8,8405,"陕西分"],[76.2,66.8,75,"内蒙古分"],[76.2,null,75,"内蒙古分001"],[null,66.8,75,"内蒙古分002"],[76.2,66.8,null,"内蒙古分003"],[76.2,null,75,"内蒙古分004"]],
        dimensions:['采购价格','销售价格','销量','分公司名称']
    },
