   the code is like this
   
   ``let num = 0;
   
   useEffect(() => {
   if(num > 0){
   let dom = document.getElementById('chart');
   let myChart = echarts.init(dom)
   myChart.setOption(...);
   }
   
   }, [num]);
   
   {num === 0 ? (
   <div id='chart' style={{width: '200px', height: '200px'}}></div>
   ) : (
   <div>
   暂无数据
   </div>
   )}``
