1、在页面中加入ref

<div  class="echart_income" ref="echartsWaring"></div>

2、去掉echarts渲染出来的属性_echarts_instance_

initChart() {//移除图表中_echarts_instance_属性this.$refs.echartsWaring.removeAttribute('_echarts_instance_')let getchart = echarts.init(this.$refs.echartsWaring);getchart.setOption(lineOption);//随着屏幕大小调节图表window.addEventListener("resize", () => {getchart.resize();});},

另外一种情况，当点击切换tab时echarts图表缩小在一起（宽高只有100px）的解决方法

在点击tab切换时添加事件

handleClick(){this.$nextTick(()=>{window.dispatchEvent(new Event("resize"));})},
