I have studied the sample in below link : http://www.igniteui.com/data-chart/polar-series
In this sample(PolarLine), I couldn't know that which is the first point and which is the last point. Can we add an arrow to show the direction explicitly.
Hello Charlie,
Thank you for contacting Infragistics Developer Support!
This is a chart that uses circular type of coordinate system - Polar coordinate system. In circle you do not have beginning or end. So generally to your question the marked point is neither first or last point. However there is order how the points are connected them. The connection order is the same as the order in the data source, so basically it start connecting the points from this point relative to the data source.
Let me know if you need further assistance.
Hello Denis ,
Thanks for your quick response.
But I have the requirement to show which point is the beginning. Can I mark the beginning point's marker with different color ?
I'm just following up to see if you need any further assistance with this issue. If so please let me know.
