StackViewBarChart

Create a simple bar chart with UIStackView, because...why not?

UIStackView is my favorite AutoLayout tool now, so part of the project's goal is to explore UIStackView's capability. It turns out it is fairly easy to create a bar chart with UIStackView.

Features

Customize chart legends
Implemented completely with UIStackView
Gradual bar color
Tiny code base (only 2 view classes)
Easy to folk and modify to use in your project

Usage

Adding the StackViewBarChart to your project:

There are two ways to add the ScrollableGraphView to your project.

Manually

Add all of the files in the Classes directory to your project in Xcode to your project in Xcode.

Carthage

Add to your Cartfile:

github "haojianzong/StackViewBarChart" ~> 0.5.3

Then make sure to link the frameworks and import StackViewBarChart in your code.

CocoaPods

CocoaPods is not supported

Creating a bar chart with data.

Create a StackViewBarChart instance then set its numberList property with custom data.

```swift
class ViewController: UIViewController {

    // Initialize an instance
    let barChart = StackViewBarChart(frame: .zero)

    override func viewDidLoad() {
        super.viewDidLoad()

        // Setup its frame
        view.addSubview(barChart)
        barChart.frame = CGRect
        barChart.frame = CGRect(x: 0, y: 0, width: 300, height: 300)

        // Set the data
        barChart.dataList = [
          .init(legend: "M", number: 0),
          .init(legend: "T", number: 2),
          .init(legend: "W", number: 7),
          .init(legend: "T", number: 8),
          .init(legend: "F", number: 30),
          .init(legend: "S", number: 20),
          .init(legend: "S", number: 10)
    }
}
```
