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.
Comment 2 pep jorge 2015-06-26 05:39:27 EDT 
As a workaround just set Chart.Zoom.Active = true; as by default is set to false.
