Can you explain why this action should only be dispatched for axis triggers?

I found this action causes the emphasis state lost.
After dispatch:
Expected:
Maybe dispatch this action only when axisPointer is enabled would be better.
Is there any way to check if axisPointer is enabled or not?

Logically speaking, I don't think whether the axisPointer is enabled makes any difference in this regard. If we consider that setOption should lead to an update of the tooltip, then it is also logical that setOption causes the emphasis state to become updated.
This is also one of the reasons why I'm more inclined to think that the issue in this PR isn't a bug. Perhaps keeping the setting of "changing the 'trigger' via setOption won't trigger the redrawing of the tooltip" would simplify matters. May I ask what initially led you to need to fix the problem in this PR?

I will revert this change because you think losing the "emphasis" is not a bug.
But changing the tooltip "trigger" without updating the tooltip is certainly a bug.

@Ovilia I've updated the code accordingly. Could you help to review again? Thanks! |
