hello.

I'm using .Net Vision Chart.

However, I want add a vertical cursor at my Smooth Line chart.
I saw some data cursor example which is applied NLineseries and NStepLineSeries.
These serieses have 'IntersectWithXValue' and 'IntersectWithYValue'. But, NSmoothLineseries don't have any intersect method.

As a result, I want add a vertical cursor and a data point on the smooth line such as your NLineSeries, NStepLineSeries examples ( 'Intersect Line with X/Y Value', 'Step Line Intersection'). How can I do?
