[GitHub] [incubator-echarts] Ovilia commented on issue #11789: Symbol display interval is not correct when sampling is enabled.

Ovilia commented on issue #11789: Symbol display interval is not correct when sampling is enabled.
URL: https://github.com/apache/incubator-echarts/issues/11789#issuecomment-599934299
 
 
   This is caused by:
   1. When `symbolSize` is set to be too small, [canShowAllSymbolForCategory](https://github.com/apache/incubator-echarts/commit/aad1e1cf7d9829b2cfc5f35bbe3443b1b4dfd53a#diff-cce4eb3566bf44149635dafef0869e53R323) returns true but labels are too crowded in this case.
   2. Due to sampling, some points are not visible so that their labels are not shown. But should we display nearby labels? This should also be discussed more in 5.0.
   
   Label collision detection should be improved in 5.0. For now, we'd advice to set `showAllSymbol` to be false when sampling.
