    Hello,

    Is there any event related to zoom changed? (both with zoom bars and with mouse). Thanks.

    Hello Timo,

    Currently RadChartView does not expose public pan/zoom events -- we have already logged this feature request in our public issue tracking system here and will forward your feedback to our developers for further consideration (you can aslo vote on the PITS item to raise its priority).

    If you are using MVVM you can expose pan/zoom related properties on your view model and use two-way bindings to the cartesian chart properties so you will receive notification that pan/zoom chart property is changed in your view model.

    We have attached a sample application that demonstrates this approach (check ViewModel.Zoom for zoom and ViewModel.RangeStart / RangeEnd for pan).


    Kind regards,
    Giuseppe
