   你好，我代码结构大概是这样：export default Vue.extend({
   &nbsp; &nbsp; &nbsp; &nbsp; data(){return{}},
   
   
   &nbsp; &nbsp; &nbsp; &nbsp; methods:{
   &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;functionA(){&nbsp; data = update_data() }
   &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;................
   &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;functionN(){}
   
   
   &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;build_chart(){
   &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;let mychart = this.$echarts.init()
   &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;option = {.........}
   &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;mychart.option(option)
   &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;setInterval(function () {
   &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;myChart.setOption({
   &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;series: [{data: data}]});
   &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;}, 1000);
   &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }
   &nbsp; &nbsp; &nbsp; &nbsp;},
   
   
   &nbsp; &nbsp; &nbsp; &nbsp;mounted(){
   &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;build_chart();
   &nbsp; &nbsp; &nbsp; &nbsp;},
   })
   麻烦帮我看下哪里需要修改

   @BUERGER123 建议先用这个代码写个最简单的例子排查下是不是 echarts 的问题
    
   vue 和 echarts 结合使用的时候需要注意不要把 echarts 实例或者配置项挂到 vue 下面，vue 会深度遍历监听所有属性，数据量一下就卡了
