Corgis opened a new issue #15333:
URL: https://github.com/apache/echarts/issues/15333


   ### Version
   5.1.2
   
   ### Reproduction link

   ### Steps to reproduce
   打开页面，拖动visualMap，坐标上未正确显示在该范围内的点，而是全部显示了，且点的颜色和visualMap的颜色不一样
   
   ### What is expected?
   希望拖动visualMap，坐标上能够正确显示在该范围内的点，且点的颜色和visualMap应该一致
   
   ### What is actually happening?
   拖动visualMap，坐标上未正确显示在该范围内的点，而是全部显示了，且点的颜色和visualMap的颜色不一样

   经测试是 开启了 large：true 大数据优化的问题 将large:false则不会出现该bug

   开启 large 后为了性能无法再支持每个点取不同的样式，这是一个需要取舍的配置项，不然我们就默认开启了

   @Corgis 透明度为 0 是样式设置的一部分，large 模式下每个点自己的样式实际是被忽略了，所以不会因为透明度为 0 而不显示。后面可以考虑为这种场景做下特殊处理

   嗯，感谢你们提供这么优秀的框架，和及时的回复，谢谢，不过我觉得这可能是个bug，如果是透明度渲染成0，应该不会显示范围外的点才对，但问题描述中的链接里，当visualMap的区间拖动到[ -100 , -100 ] 这个的时候，按道理图上应该是很少的点甚至没有点，但现象是铺满了点.

   点的颜色设置这个可以理解，但大数据优化后 visualMap 范围拖动为什么点的渲染会有问题呢？具体你可以看我上面的demo链接

   @Corgis 这是因为范围外的实际上是被编码成透明度为 0 了，也算是不同的样式，不过这点确实可以优化下
