onBeforeSort

Event name is case insensitive.

This event calls user-defined handlers (if there are any) and passes the following parameters:

  • by - a template of sort-by field
  • dir - a direction of sorting
  • as - a type of sorting
chart.attachEvent("onBeforeSort", function (by, dir, as){
//any custom logic here
});

Event can be blocked, returning false will prevent normal reaction of component.
