I assume that you have checked our polar chart
and you have found it not to be suitable. If you have not yet explored it, please do before continuing.
I understand that you are using the RadCartesianChart
and you need some sort of a elliptical annotation. The cartesian chart does not support oval annotations, but I think that you can easily achieve the desired results by using a custom adorner and making use of the PlotAreaClipChanged
event and the conversion
api of the chart. I have attached a small project to better demonstrate the suggestion. Let us know how it goes!
