addSplineAreaLayer(data[, color[, name ]])

Add a polar spline area layer to the polar chart.

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

Argument	Default	Description
data	(Mandatory)	An array of numbers representing the data points in the layer.
color	-1	The color to draw the data points. -1 means that the color is automatically selected from the palette.
name	""	The name of the layer. The name will be used in the legend box, if one is available. An empty string means the layer has no name.

A PolarSplineAreaLayer object representing the polar spline area layer created.
