1、要实现的效果如下图：

2、首先项目中引用vue2-highcharts

package.json中如下：

在命令行中输入：

cnpm install vue2-highcharts

3、页面代码如下：

<template>
 <div >
  <div>
  <div id="transparent-header" class="rank-head container" >
    <img src="../assets/index/back.png" class="rank-head-back" @click="routerback"/>
    <span >用能排名</span>
  </div>
  </div>
  <div >
   <div >
    <datepicker v-on:picked="picked" style="margin-left:10px;"></datepicker>
   </div>
    <div >
    </div>
  </div>
  <div >
   <div class="charts">
     <vue-highcharts :options="options" ref="maxlinecharts"></vue-highcharts>
   </div>
  </div>
  <div >
   <div class="charts">
     <vue-highcharts :options="options" ref="minlinecharts"></vue-highcharts>
   </div>
  </div>
 </div>
</template>
<script>
