Dataset

Dataset is a [CAShapeLayer] (https://developer.apple.com/library/mac/documentation/GraphicsImaging/Reference/CAShapeLayer_class/index.html) subclass and thus you can change it's strokeColor and fillColor properties among others.

var data: [CGFloat]

var color: CGColor

This is a convenience property which, when set, will (a) set the strokeColor to given color and (b) set the fillColor to a very transparent version of the given color, and (c) update the defaultPoint fillColor and (d) update the legendMarker fillColor

var legendElement: CALayer
var legendMarker: CAShapeLayer
var legendLabel: CATextLayer
