    I am working on Winform Chartview and am using LassoZoomController to zoom in and out.

    My problem right now is when zooming in, I need to know the Axis' ranges for both X and Y, however I don't see any events that I can register to to detect the zooming. Also how could I know the new ranges after zooming?

    Please help! (R3 2016)

    Hello Youfei,

    Thank you for writing.

    The zoom and pan events are defined within the RadChartView.View object. You can subscribe to them this way:
    this.radChartView1.View.ZoomChanged += View_ZoomChanged;

    The documentation will be also updated to provide information on how the events can be subscribed. As to your other question please check the other thread you have opened:

    I hope this information was useful. Should you have further questions please do not hesitate to write back.
