echart的编辑

1. 做echart最好的方法，从需求出发，查看文档配置项。一边查阅，一边实现功能。一些特殊功能实现，就另说了。

<div class="upshow_left" id="seven_day_chart" style="60vw;height:38vh;"></div>

console.log(echarts +"我的图表对象");
   var seven_day_chart = echarts.init(document.getElementById('seven_day_chart'));
   //配置图表配置项
   var option_1 = {
       title:{
           text:"近7日作业情况",
           textStyle:{
               color:'#FFFFFF',
               fontSize:20,
           },
           padding:[
               20,0,0,60
           ]
       },
       legend: {
           type:'plain',
           top:"20%",
           right:"0",

           textStyle:{

       tooltip: {},
