The PolarSplineAreaLayer class represents polar spline area layers. PolarSplineAreaLayer is a subclass of PolarAreaLayer.

PolarSplineAreaLayer objects are created by using PolarChart.addSplineAreaLayer.

Method	Inherited	Description
setTension	(Self)	Set the tension to use when computing the spline curve.
setAngles	PolarLayer	Set the angular coordinates of the data points.
setBorderColor	PolarLayer	Set the border color for drawing the data on the layer.
setLineWidth	PolarLayer	Set the line width of lines when drawing the data on the layer.
setDataSymbol	PolarLayer	Use one of the built-in symbols as the graphics symbol to plot the data points.
setDataSymbol2	PolarLayer	Load an image from a file and use it as the graphics symbol to plot the data points.
setDataSymbol3	PolarLayer	Use a DrawArea object as the graphics symbol to plot the data points.
setSymbolScale	PolarLayer	Set the size of the symbol for each data point (for creating bubble charts).
setImageMapWidth	PolarLayer	Set the effective size of a data point for producing image maps.
getImageCoor	PolarLayer	Get the image map coordinates of a data point.
getHTMLImageMap	PolarLayer	Generate the HTML image map for all data points on the layer.
setDataLabelStyle	PolarLayer	Enable data labels and set their styles.
setDataLabelFormat	PolarLayer	Set the data label format.
addCustomDataLabel	PolarLayer	Add a custom data label to a data point.
