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.
