Description narcís calvet 2015-06-26 04:20:24 EDT

Double tapping on a chart in a Xamarin.Forms application on iOS throws an exception at the UndoZoom() method in the Steema.TeeChart.Chart class. It works fine in Android.

Comment 1 narcís calvet 2015-06-26 05:02:18 EDT

This happens because zoom class instance is null. Zooming the chart before double-tapping on it prevents the crash.

As a workaround just set Chart.Zoom.Active = true; as by default is set to false.
