1. 基础三件套

<div class="equipmentPie"></div>

.equipmentPie {
    width: 100%;
    height: 30vh;
 }

let echart = this.$echarts.init(document.querySelector(".equipmentPie"));
echart.setOption({
  tooltip: {
    
  },
  legend: {
 
  },
  series: [
    
  ]
});

2. 解决问题

lightChart: null,

this.lightChart =  this.$echarts.init(document.querySelector(".equipmentPie"));
this.lightChart.setOption({
  tooltip: {
    
  },
  legend: {
 
  },
  series: [
    
  ]
});

关键点

this.lightChart ? this.lightChart.dispose() : null;
