YOChartImageKit

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

Installation

CocoaPods

use_frameworks!

pod 'YOChartImageKit', '~> 1.1'

Carthage

github "yasuoza/YOChartImageKit" ~> 1.1

CocoaSeeds

# For both iOS and watchOS framework
target 'YOChartImageKit' do
  github 'yasuoza/YOChartImageKit', '1.1.0', files: 'Source/YOChartImageKit/*.{h,m}'
end

Configuration

Following section describes the way to draw charts.
If you want to try YOChartImageKit, open YOChartImageKit.xcodeproj. Example applications are available for iOS and watchOS.

Line chart

solid

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

smooth

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

Bar chart

Vertical

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

Horizontal

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

Donut chart

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
