Trackball Behavior - ActivationMode.longPress AND ActivationMode.singleTap

Question

Is it possible to get both of these activation mode behaviors at once? On single tap I'd like the trackball and information to show up, and it a user holds down I'd like it to stay up for scanning across the current range with the trackball.

Thanks!

Hi Cory Davis, 
 
Greetings from Syncfusion. We have analyzed your query and you can’t use both the activation mode of trackball at a time, however we would like to let you know that our series is having onPointTap, onPointLongPress, and onPointDoubleTap callbacks to get the data point information. Also, we are having show, showByIndex and hide public methods, using this you can show the trackball tooltip.  
 
We suggest using to show the trackball using the ActivationMode.singleTap and get the point information using onPointLongPress callback. Find the user guide below,
