vue添加多个echart组件

怎么把好几个echart柱状图、饼状图放在一个vue里面？页面也没报错，就是显示不出来
vue代码如下：

<template>
  <div class="myChart">
  <div id="barChart" :style="{width: '800px', height: '600px'}">
  </div>
    <div id="pieChart" :style="{width: '800px', height: '600px'}">
    </div>
  </div>
</template>

<script>
export default{
  name: 'ECharts',
  mounted() {
    this.myChart1();
    this.myChart2();
  },
  methods:{
    myChart1()
    {
      // 基于准备好的dom，初始化echarts实例
      let myChart1 = this.$echarts.init(document.getElementById('barChart'))
      myChart1.option = {
        title: {
          text: '水果销量统计',
          left: 'center',
          top: 20,
          textStyle: {
            color: '#555555'
          }
        },
        tooltip: {},
