   可以的，
   
   this.myChart = echarts.init(document.getElementById('observable-chart' + this.index));   // 实例化
   const url = this.myChart.getDataURL({
           pixelRatio: 2,
           backgroundColor: '#fff'
         });
   
   下载 
    downLoadChart(url) {
       const a = document.createElement('a');
       a.setAttribute('href', url);
       a.setAttribute('download', 'export');
       a.style.visibility = 'hidden';
       document.body.appendChild(a);
       a.click();
       document.body.removeChild(a);
     }
