tracking hook

In the old version we had two diffrent functionalties in tracking

• onMove : track mouse coordinates
• onClick : get closest point coordinates

i'm not sure why we didn't create simple hook for tracking

Because it's not clear yet what a common use case for tracking is. We don't know yet what to aim for so we decided to only have an example for this, not an additional api.

Also note that it's quite expensive to track the closest value on big series, so a generic hook that tracks everything could be problematic performance-wise.
