I'm re-visiting our previous approach to create an arrow annotation, as our current one is  clunky - a line with a shape appended to the end of it to emulate an arrow. It doesn't scale well with zooming in and out and our QA folks are asking for a better implementation.

Is there any add-on widget to achieve an arrow annotation in a RadCartesianChart ?

Is there a newer Chart that has arrow annotations built in ?

Thanks,

Barry

Hello Barry,

No, there is no arrow annotation provided with RadChartView. To achieve you can use a chart annotation or a custom element placed above the chart. In any case you will need to manually calculate the arrow's size when you zoom the chart. 

I've attached a small example showing a possible approach. I hope it helps.
