Currently RadChart provides only a ScatterPointSeries which does not support categorical axes and you can only use a numerical one.

Thank you for your comment. Indeed, this is supported on native iOS Chart control ( which is wrapped in Xamarin.Forms), however, as you pointed out it is not available for native Android Chart. That's why we're considering it as a feature request for Chart for Xamarin.

Strangely, I try this (CategoricalAxis for XValue and NumericalAxis for YValue) on iOS and works fine, but not on Android.
Hope this info would help, so you can just try to figure out the chart on Android platform (dont know on Windows), which could be easier.
