Since watchOS does not have UIView class, YOChartImageKit draws a UIImage of a chart with given values.
Values and colors can be customized.

endFollowing section describes the way to draw charts.
If you want to try YOChartImageKit, open YOChartImageKit.xcodeproj. Example applications are available for iOS and watchOS.
let image = YOLineChartImage()
image.strokeWidth = 4.0 // width of line
image.strokeColor = randomColor() // color of line
image.values = [0.0, 1.0, 2.0] // chart values
image.smooth = false // disable smooth line
image.drawImage(frame, scale: scale) // draw an image
let image = YOLineChartImage()
image.strokeWidth = 4.0 // width of line
image.fillColor = randomColor() // color of area
image.values = [0.0, 1.0, 2.0] // chart values
// image.smooth = true // [default] draws a smooth line
image.drawImage(frame, scale: scale) // draw an image
let image = YOBarChartImage()
image.values = [0.0, 1.0, 2.0] // chart values
image.fillColor = randomColor() // color of bars
// image.barPadding = 2.0 // [optional] padding of bars
// image.barStyle = .Vertical // [default] draws a vertical bars
image.drawImage(frame, scale: scale) // draw an image
let image = YOBarChartImage()
image.values = [0.0, 1.0, 2.0] // chart values
image.fillColor = randomColor() // color of bars
// image.barPadding = 2.0 // [optional] padding of bars
image.barStyle = .Horizontal // draws a horizontal bars
image.drawImage(frame, scale: scale) // draw an image
let image = YODonutChartImage()
image.donutWidth = 16.0 // width of donut
// image.labelText = "LABEL" // [optional] center label text
// image.labelColor = UIColor.whiteColor() // [optional] center label color
image.values = [10.0, 20.0, 70.0] // chart values
image.colors = (0..<3).map { _ in randomColor() } // colors of pieces
image.drawImage(frame, scale: scale) // draw an image- watchOS ~> 2.0
