So I am using RadCartesianChart with SplineAreaSeries to simulate the oceans tide. I am using DateTimeContinuousAxis as my horizontal value and the tide height as my vertical value. The chart draws great curves, but I cannot find a way to get the path details from the chart that is drawn. What I am trying to do is have an object move itself across the Spline on a timed interval. The object will show the tides height in the middle of it.
So here are my questions.
->Is there a way to find out the vertical intersection point given the horizontal value. chart.series.GetVerticalValue(HorizontalValue); So if I provide a DateTime, it will give me the vertical height value.
-> If not, are there any other ways to find out intersection points of the spline or the drawn path itself? If I could get access to that then I can duplicate a path for my object to follow.
Attached is the closest that I have come. The SplineChart is draw in blue, then I have automatically calculated the tide height at timed intervals(Green) and have the annotation follow it, but just can't make it curve to follow.
