[VB]	Public Function addSplineLayer([ data As Double() [, color As Integer [, name As String ]]]) As SplineLayer
[C#]	public SplineLayer addSplineLayer([ double[] data [, int color [, string name ]]]);

Adds a spline layer to the XYChart.

In a spline layer, the data points are connected together using cardinal spline curves (as opposed to straight lines). The "monotonicity" of the spline curve can be configured by using SplineLayer.setMonotonicity. The "tension" of the curve can be configured using SplineLayer.setTension.

Argument	Default	Description
data	[Empty_Array]	An array of numbers representing the data set.
color	-1	The color to draw the spline line. -1 means that the color is automatically selected from the palette.
name	""	The name of the data set. The name will be used in the legend box, if one is available. An empty string means the data set has no name.

A SplineLayer object representing the spline layer created.
