   > @panbinchn 卡顿的原因可能有很多，方便发我们可以复现的 case 么
   
   我的需求是根据请求回来的曲线数据（曲线配置参数和源数据）显示多组不同样式折线图，每组折线图数量不定，在页面初始渲染时会卡顿1-3秒才把曲线渲染出来。因此想请教一下，当出现我这种多曲线渲染的场景下，有没有提高曲线渲染性能的方法？希望能够得到您的指教，非常感谢！
   
   `<div
               v-for="(item1, index1) in chartData"
               :key="index1"
               class="chartBox"
               :id="item1.chartType"
               :class="item1.chartType"
               v-show="isChartType==item1.chartType"
             >
               <lineChart
                 v-for="(item2, index2) in item1.chartList"
                 :key="index2"
                 :chartIndex="index2"
                 :chartConfig="item1.chartConfig"
                 :chartSeries="item2.data"
               ></lineChart>
             </div>`
