Hi i m using XYsplineRender along with XYPlot.... to draw a smooth curve graph instead of line chart

suppose i m using the points (1,2) (2,4) (3,1) (3,8) and (4,5) for drawing the curve ....the curve is drawn with four point only and the point (3,8) is ignored while joining the curve....ie the curve doesnt pass through (3,8).But for my application i want the curve to pass through all the points.....is there any way to make the curve pass through all the points.Pls help

The underlying algorithm for the Splines only allows unique X-values.

Imagine the spline for your case - it would look like an 'S' around x=3, i.e. curling back on itself.
