如何让四个图表以轮播图的样式展示，切换？

直接用element中Carousel 走马灯实现

<el-carousel arrow="always" :autoplay="false" indicator-position="none">
  <el-carousel-item v-for="item in array" :key="item">
      <eChartid v-if="xData && item === 1" :xData="xData"></eChartid>
      <CharTok v-if="charData && item === 2" :charData="charData"></CharTok>
      <ChartReuse v-if="useData && item === 3" :useData="useData"></ChartReuse>
      <ChartOrowid v-if="owiData && item === 4" :owiData="owiData"</ChartOrowid>
  </el-carousel-item>
</el-carousel>

` array: [1, 2 ,3 ,4],
