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
