Make highcharts display the tooltip of the previous point

问题

Is there a way in Highcharts to cause the tooltip to be displayed not by the closest point to the mouse but always by the point to the left?
e.g in the picture below, I want that if the mouse is hovering the red area the tooltip that would be displayed is the tooltip of the point above May:

Thanks :)

You can use tooltip Positioner which allows you to define your own positioning function.
