Hi!
I'm using the latest release 16.3.0.21.
This issue is the same as https://www.syncfusion.com/forums/124346/winrt-sidebysideseriesplacement-issue-when-series-have-hourly-data
but in Xamarin.Forms (iOS app).
SideBySideSeriesPlacement=false does allow me to overlap columns when Interval is set to Days automatically,
but at Hours type seems completely broken. I don't attach any screenshot because by problem looks exactly the same as linked above.
This is for iOS 12 but probably other iOS versions too.
