Installation

CocoaPods

Add the following line to your Podfile:

pod "MLLineChart"

$ pod install

Dependency Managers

CocoaPods

CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:

$ gem install cocoapods

To integrate MLLineChart into your Xcode project using CocoaPods, specify it in your Podfile:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '10.0'
use_frameworks!

pod 'MLLineChart', '~> 2.0.5'

Then, run the following command:

$ pod install

Carthage

Carthage is a decentralized dependency manager that automates the process of adding frameworks to your Cocoa application.

You can install Carthage with Homebrew using the following command:

$ brew update
$ brew install carthage

To integrate MLLineChart into your Xcode project using Carthage, specify it in your Cartfile:

github "micheltlutz/MLLineChart" ~> 2.0.5

Manually

If you prefer not to use either of the aforementioned dependency managers, you can integrate MLLineChart into your project manually.

Git Submodules

Open up Terminal, cd into your top-level project directory, and run the following command “if” your project is not initialized as a git repository:

$ git init

Add MLLineChart as a git submodule by running the following command:

$ git submodule add https://github.com/micheltlutz/MLLineChart.git
$ git submodule update --init --recursive

Open the new MLLineChart folder, and drag the MLLineChart.xcodeproj into the Project Navigator of your application’s Xcode project.

It should appear nested underneath your application’s blue project icon. Whether it is above or below all the other Xcode groups does not matter.
Select the MLLineChart.xcodeproj in the Project Navigator and verify the deployment target matches that of your application target.
Next, select your application project in the Project Navigator (blue project icon) to navigate to the target configuration window and select the application target under the “Targets” heading in the sidebar.
In the tab bar at the top of that window, open the “General” panel.
Click on the + button under the “Embedded Binaries” section.
You will see two different MLLineChart.xcodeproj folders each with two different versions of the MLLineChart.framework nested inside a Products folder.

It does not matter which Products folder you choose from.
Select the MLLineChart.framework.
And that’s it!

The MLLineChart.framework is automagically added as a target dependency, linked framework and embedded framework in a copy files build phase which is all you need to build on the simulator and a device.

Embedded Binaries

Download the latest release from https://github.com/micheltlutz/MLLineChart/releases
Next, select your application project in the Project Navigator (blue project icon) to navigate to the target configuration window and select the application target under the “Targets” heading in the sidebar.
In the tab bar at the top of that window, open the “General” panel.
Click on the + button under the “Embedded Binaries” section.
Add the downloaded MLLineChart.framework.
And that’s it!

     private var lineChart: MLLineChart!
    private var dataEntries: [MLPointEntry] = []
    var widthChart = CGFloat(320)
    var heightChart = CGFloat(275)
    
    override func viewDidLoad() {
        super.viewDidLoad()
        makeData()
        setupChart()
    }

    private func makeData() {
        dataEntries.append(MLPointEntry(value: 5, label: "1", color: .gray))
        dataEntries.append(MLPointEntry(value: 6, label: "2", color: .green))
        dataEntries.append(MLPointEntry(value: 4, label: "3", color: .blue))
    }

    private func setupChart() {
        lineChart = MLLineChart(frame: CGRect(x: 0, y: 0, width: widthChart, height: heightChart))
        lineChart.translatesAutoresizingMaskIntoConstraints = false
        lineChart.dataEntries = dataEntries

        lineChart.showShadows = true
        lineChart.showAxisLine = true
        lineChart.gradienLinesColors = [UIColor.gray.cgColor, UIColor.green.cgColor, UIColor.blue.cgColor]
        lineChart.configLabelsBottom = MLLabelConfig(color: .white,
                                                           backgroundColor: .gray,
