Usage
#####import Graphs
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)

Issues
GraphView doesn’t work on Interface builder.
Interface Builder talks to code through the ObjC runtime.
And ObjC doesn’t do generics.
