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

PolarAreaLayer objects are created by using PolarChart.addAreaLayer.

setBorderColor	PolarLayer	Sets the border color for drawing the data on the layer.
setLineWidth	PolarLayer	Sets the line width of lines when drawing the data on the layer.
setDataSymbol	PolarLayer	Uses 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	Uses a DrawArea object as the graphics symbol to plot the data points.
setDataSymbol4	PolarLayer	Uses a custom polygon as the graphics symbol to plot the data points.
setSymbolOffset	PolarLayer	Offset the symbols in the x and y directions in pixel unit.
setSymbolScale	PolarLayer	Sets the size of the symbol for each data point (for creating bubble charts).
