I need to detect when a visitor is using the zoom handles to set a dropdown outside of highcharts to a default option. The default option should appear as soon as the user moves one of the handles.
I tried with the afterSetExtremes event but it also detects when the user is clicking a rangeSelector button or using the date field...
Code: Select all
xAxis: {
events: {
afterSetExtremes: function(){
// detect only use of handles?
}
},
}
How can I detect only when the user is pressing on one of the handles? Something like "onMouseUp"?
Thank you in advance for your help!
