// 竖向的正常百分比即可
.vertical {

  height: 100%;
}
/* 用于给横向echarts画布定位用,横向就旋转90度即可 */
.horizontalEchartsFather {
  transform: rotate(90deg);
  position: relative;
  width: 100%;
}
// 因为横向了,所以颠倒一下
.horizontal {
  width: 100vh;
  height: 100vw;
}
/* 进入横屏和退出横屏两套样式,定位在不同的位置 */
.verticalIcon {
  position: absolute;
  top: 2px;
  right: 6px;
  z-index: 999;
  user-select: none;
}
.horizontalIcon {
  position: absolute;
  top: 2px;
  left: 6px;
  z-index: 999;
  user-select: none;
}
</style>

总结

横屏的时候,即为竖屏旋转90度,加上监听控制,然后改一下样式,最后别忘了重绘一下Echarts
