mpvue使用echarts，绘制多个图形

<div class="minekpi">
    <p class="selects">
      <span @click="selectedech">
        当月
        <img src="/static/images/arrow_low.png" alt />
      </span>
    </p>
    <div class="salevolume">本月销售额</div>
    <div class="echarts1">
      <mpvue-echarts :echarts="echarts" :onInit="pieInit" canvasId="pie" />
    </div>
    <p class="salevolumetitle">全店占比</p>
    <div class="content">
      <div class="view">
        <p class="num">{{ownamount}}</p>
        <p>销售额(元)</p>
      </div>
      <div class="view view1">
        <p class="num">{{amountrank}}</p>
        <p>全店排名</p>
      </div>
    </div>

    <div class="salevolume">本月交易数</div>
    <div class="echarts1">
      <mpvue-echarts :echarts="echarts" :onInit="pieInit2" canvasId="pie2" />
    </div>
    <p class="salevolumetitle">全店占比</p>
    <div class="content">
      <div class="view">
        <p class="num">{{ownaquantity}}</p>
        <p>销售数(笔)</p>
      </div>
      <div class="view view1">
        <p class="num">{{quantitytrank}}</p>
        <p>全店排名</p>
      </div>
    </div>
  </div>

　　引入echarts，如果打包过大需要分包可以将echarts.min.js到echarts官网定制压缩代码
