Pick up points( or a specific point) from box zoom

Dear all,

I want the data points returned back in somewhere or extracted from those JS codes after I zoom in/out in the box zoomed.

What have you tried that did NOT work as expected?
I use “CustomJS for selections” and it shows data of what I selected in a box. However, it just a picture,not data I can operate.

Further, this is not my original intention. I was going to just return data points in the selected box (for pick up maximum).

Many thanks for your supports

Hi @DellFan there is not enough information here to speculate. We really need you to provide a complete Minimal Reproducible Example to actually study and investigate.
