From v2.5
onwards parameters of onHover callback has been changed. See PR#3669
onHover callback now has 3 parameters. The 2nd parameter is the event
that triggered the hover. This was done for consistency with the
onClick callback.
function(event, activeElements) {
}
Previously, activeEvents was the first argument, and event was not passed.
You can check release notes of v2.5
So you’ve to change your onHover callback
as follows:
onHover: function(event,elements) {
$("#canvas1").css("cursor", elements[0] ? "pointer" : "default");
}
