# SwiftPieChart

Simple and elegant pie chart for Swift UI

![SwiftUI Pie Chart](https://raw.githubusercontent.com/ilamanov/SwiftPieChart/main/Resources/demo.gif "SwiftUI Pie Chart")

## Usage

```swift
import SwiftPieChart

...

PieChartView(
    values: [1300, 500, 300],
    names: ["Rent", "Transport", "Education"],
    formatter: {value in String(format: "$%.2f", value)})
```

`formatter` is used to format the values for displaying purposes. In the example above we are displaying values with 2 decimal places and with the `$` sign in the front.

## Installation

In Xcode go to `File -> Swift Packages -> Add Package Dependency` and paste in the repo's url: `https://github.com/ilamanov/SwiftPieChart`

## Demo

A demo iOS app shown in the gif above can be found at https://github.com/ilamanov/SwiftPieChartDemo

## Easy Customization

You can change the width of the pie chart by providing `widthFraction` parameter:

    names: ["Rent", "Transport", "Education"],
    formatter: {value in String(format: "$%.2f", value)},
    widthFraction: 0.95)
```
