rederick opened a new issue #11356: About HeatMap  Slowly Loading
URL: https://github.com/apache/incubator-echarts/issues/11356
 
 
   ### What problem does this feature solve?
   https://www.echartsjs.com/examples/zh/editor.html?c=heatmap-large,When we load more than 20000 points in this page, we can see it a little bit slow. If we need show more points, such as 200000(2000*100) points,  we cannot let the customer wait a long time.
   
   ### What does the proposed API look like?
   In my situation, the most data is almost over 80% data is same, but others maybe abnormal. I'm not sure you have already done some optimization. So I suggest, could you have time to update the heatmap control, at first to fill the whole container with the average color, then just cycle the data, when the data class is not the average one, update the small rectangle. It should save some time. If the graph can show less than one second, even we cannot find it loading, I think it will be nice to all of us.
