Usage

import Graphs

Range -> GraphView (Bar)

let view = (1 ... 10).barGraph(GraphRange(min: 0, max: 11)).view(viewFrame)

Array -> GraphView (Line)

let view = [10, 20, 4, 8, 25, 18, 21, 24, 8, 15].lineGraph(GraphRange(min: 0, max: 30)).view(viewFrame)

Dictionary -> GraphView (Pie)

let view = ["a": 3, "b": 8, "c": 9, "d": 20].pieGraph().view(viewFrame)

GraphData protocol -> GraphView (Pie)

import Graphs
struct Data<T: Hashable, U: NumericType>: GraphData {
 typealias GraphDataKey = T
 typealias GraphDataValue = U
 
 private let _key: T
 private let _value: U
 
 init(key: T, value: U) {
 self._key = key
 self._value = value
 }
 
 var key: T { get{ return self._key } }
 var value: U { get{ return self._value } }
}
let data = [
 Data(key: "John", value: 18.9),
 Data(key: "Ken", value: 32.9),
 Data(key: "Taro", value: 15.3),
 Data(key: "Micheal", value: 22.9),
 Data(key: "Jun", value: 12.9),
 Data(key: "Hanako", value: 32.2),
 Data(key: "Kent", value: 3.8)
]
let view = data.pieGraph() { (unit, totalValue) -> String? in
 return unit.key! + "\n" + String(format: "%.0f%%", unit.value / totalValue * 100.0)
}.view(viewFrame)
