is a way to see all data in tooltip when the points are overlap with each other(or very close), but see only one data when a point is far from others

问题

For line chart tooltip, if we set "share: true", we can see all data with same X-Axis value in a single bubble. if we set "share: false", we can see only one data in single bubble.

My question is whether there is a way to see all data in tooltip when the points are overlap with each other(or very close), but see only one data when a point is far from others.
