First Step  - `import CSPieChart` to your project



Second Step - You should `CSPieChartData`. This is model for piechart.

```Swift

  let data = CSPieChartData(key: "test", value: 70)

```



Third Step - Add a delegate `CSPieChartDataSource` & `CSPieChartDelegate` to your class & add two delegate methods 

```Swift

public protocol CSPieChartDataSource {



    ///  Component data

    func numberOfComponentData() -> Int

    func pieChart(_ pieChart: CSPieChart, dataForComponentAt index: Int) -> CSPieChartData



    ///  Component colors

    func numberOfComponentColors() -> Int

    func pieChart(_ pieChart: CSPieChart, colorForComponentAt index: Int) -> UIColor



    ///  If you are implement this, you can show subView. example) 'UIImageView' or 'UILable'

    @objc optional func numberOfComponentSubViews() -> Int

    @objc optional func pieChart(_ pieChart: CSPieChart, viewForComponentAt index: Int) -> UIView



    ///  If you are implement this, you apply color to line path

    ///  Otherwish line color is applied default 'black'

    @objc optional func numberOfLineColors() -> Int

    @objc optional func pieChart(_ pieChart: CSPieChart, lineColorForComponentAt index: Int) -> UIColor

}

```

```Swift

public protocol CSPieChartDelegate {



    /// Component select

    @objc optional func pieChart(_ pieChart: CSPieChart, didSelectComponentAt index: Int)

}

```



You can set some options



```Swift

    //  Pie chart radius rate that is percentage of frames in the superview. default is 0.7

    public var pieChartRadiusRate: CGFloat = 0.7

    

    // Pie chart line length between component and subview. default is 10

    public var pieChartLineLength: CGFloat = 10

    

    //  This is piechart component selecting animation. default is none

    public var seletingAnimationType: SelectingAnimationType = .none

}

```



Last Step - You must call `show`.

### Example

```Swift

  func ViewDidLoad(...) {

      ....

      pieChart.show(animated: true)

  }

```
