 7 | Create a simple bar chart with UIStackView, because...why not?
 8 | 
 9 | 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.
10 | 
11 | ## Features
12 | 
13 | - Customize chart legends
14 | - Implemented completely with UIStackView
15 | - Gradual bar color
16 | - Tiny code base (only 2 view classes)
17 | - Easy to folk and modify to use in your project
18 | 
19 | ## Screenshots

22 | <img height="300" align="left" src="https://github.com/haojianzong/StackViewBarChart/blob/master/demo-landscape.png" />
23 | 
24 | ## Requirements
25 | 
26 | - iOS >= 12.0
27 | - Swift >= 5.0
28 | 
29 | ## Usage
30 | 
31 | ### Adding the StackViewBarChart to your project:
32 | 
33 | There are two ways to add the ScrollableGraphView to your project.
34 | 
35 | #### Manually
36 | Add all of the files in the [Classes](StackViewBarChartExample/Classes/) directory to your project in Xcode to your project in Xcode.
37 | 
38 | #### Carthage
39 | 
40 | Add to your Cartfile:
41 | 
42 | ```
43 | github "haojianzong/StackViewBarChart" ~> 0.5.3
44 | ```
45 | 
46 | Then make sure to link the frameworks and `import StackViewBarChart` in your code.
47 | 
48 | #### CocoaPods
49 | 
50 | CocoaPods is not supported
51 | 
52 | ### Creating a bar chart with data.
53 | 
54 | Create a StackViewBarChart instance then set its `numberList` property with custom data.
55 | 
56 |     ```swift
57 |     class ViewController: UIViewController {
58 | 
59 |         // Initialize an instance
60 |         let barChart = StackViewBarChart(frame: .zero)
61 | 
62 |         override func viewDidLoad() {
63 |             super.viewDidLoad()
64 | 
65 |             // Setup its frame
66 |             view.addSubview(barChart)
67 |             barChart.frame = CGRect
68 |             barChart.frame = CGRect(x: 0, y: 0, width: 300, height: 300)
69 | 
70 |             // Set the data
71 |             barChart.dataList = [
72 |               .init(legend: "M", number: 0),
73 |               .init(legend: "T", number: 2),
74 |               .init(legend: "W", number: 7),
75 |               .init(legend: "T", number: 8),
76 |               .init(legend: "F", number: 30),
77 |               .init(legend: "S", number: 20),
78 |               .init(legend: "S", number: 10)
79 |         }
80 |     }
81 |     ```  
82 |     
83 | ## Known Issues
84 | 
85 | - Only support positive numbers
86 | - Autolayout warnings when there are too many bars and the frame is too small
87 | 
88 | ## Other
