面向iOS的轻量级图表视图生成器。用Swift编写。
要求
- iOS 8.0+
- XCode 7.3+
安装
使用
导入Graphs
import Graphs范围 -> GraphView（柱状图）
let view = (1 ... 10).barGraph(GraphRange(min: 0, max: 11)).view(viewFrame)
数组 -> GraphView（折线图）
let view = [10, 20, 4, 8, 25, 18, 21, 24, 8, 15].lineGraph(GraphRange(min: 0, max: 30)).view(viewFrame)
字典 -> GraphView（饼图）
let view = ["a": 3, "b": 8, "c": 9, "d": 20].pieGraph().view(viewFrame)GraphData协议 -> GraphView（饼图）
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)

示例
$ git clone https://github.com/recruit-mtl/Graphs.git
$ cd /path/to/Graphs/GraphsExample
$ pod install然后打开GraphsExample.xcworkspace
问题
GraphView在Interface Builder上无法工作。
Interface Builder通过ObjC运行时与代码通信。而ObjC不支持泛型。
