When you declare a specific CalendarAppointmentsStyle and assign it to the AppointmentsStyle property of the RadCalendar - it is not respected. However, if you try to set it in the NativeControlLoaded event, the changes are correctly applied. Available in minor release 2018.1.405. It will also be available in the R2 2018 release.
When the chart has a lot of data, you may not necessarily want to show it all when the chart initially appears, but you may want to show the chart in a semi-zoomed state. Therefore, there should be properties which govern the ranges by which the chart should appear zoomed initially. So, the end-user should be able to zoom in/out starting from this state and then return to the same state if necessary (avoiding getting the whole data if he zooms out too much).
Bring the LabelRotationAngle property to Axes in Xamarin.Forms. See LabelRotationAngle here for reference: http://docs.telerik.com/devtools/wpf/controls/radchartview/axes/axis
Bars are too thin in iOS when items are per day.

Allow the user to customize the origin of rotation for axis labels.
Currently, depending on the platform, the first piece of the pie is drawn at 3 or 9 o'clock. It should be possible for the developer to set the starting point to be 12 o'clock.
Provide more control over the series rendering
Currently the Annotation is always rendered on top of the series. Add a feature that will allow setting the series above the chart annotation.
