Version 3.0, synced to MPAndroidChart #1b9b3da

alt tag Supported Platforms Releases Latest pod release Carthage compatible Build Status Join the chat at https://gitter.im/danielgindi/Charts

Just a heads up: We've renamed from ios-charts to Charts.

  • Xcode 7.3 / Swift 2.2 / 3.0
  • iOS 8.0 / 9.0 (Use as an Embedded Framework)
  • tvOS 9.0
  • OSX 10.11

Okay so there's this beautiful library called MPAndroidChart by Philipp Jahoda which has become very popular amongst Android developers, and in the meanwhile there's no decent charting solution for iOS.

I've chosen to write it in Swift as it can be highly optimized by the compiler, and can be used in both Swift and ObjC project. The demo project is written in ObjC to demonstrate how it works.

An amazing feature of this library now, for Android, iOS, tvOS and OSX, is the time it saves you when developing for both platforms, as the learning curve is singleton- it happens only once, and the code stays very similar so developers don't have to go around and re-invent the app to produce the same output with a different library. (And that's not even considering the fact that there's not really another good choice out there currently...)

Usage

In order to correctly compile:

  1. Drag the Charts.xcodeproj to your project
  2. Go to your target's settings, hit the "+" under the "Embedded Binaries" section, and select the Charts.framework
  3. Temporary workaround: Xcode 6.3.1 has a bug, where you have to build your project once before actually writing the @import line. So hit "Build" now!
  4. @import Charts
  5. When using Swift in an ObjC project:
    • You need to import your Bridging Header. Usually it is "YourProject-Swift.h", so in ChartsDemo it's "ChartsDemo-Swift.h". Do not try to actually include "ChartsDemo-Swift.h" in your project :-)
    • Under "Build Options", mark "Embedded Content Contains Swift Code"
  6. When using Realm.io:
    • Note that the Realm framework is not linked with Charts - it is only there for optional bindings. Which means that you need to have the framework in your project, and in a compatible version to whatever is compiled with Charts. We will do our best to always compile against the latest version.

If you want to compile for iOS 7:

  1. Drag the code itself (.swift files) to your project. As sadly, Swift currently does not support compiling Frameworks for iOS 7.
  2. Make sure that the files are added to the Target membership.

Troubleshooting

Can't compile?

  • Please note the difference between installing a compiled framework from CocoaPods or Carthage, and copying the source code.
  • If you are using Realm, please also #import <ChartsRealm/ChartsRealm.h>
  • If you are compiling the source code and want to use Realm, please make sure to include the code from ChartsRealm project.
  • Please read the Usage section again.
  • Search in the issues
  • Try to politely ask in the issues section

CocoaPods Install

Add pod 'Charts' to your Podfile. "Charts" is the name of the library.

For Realm support you can specify the subspec in your Podfile as follows:

pod 'Charts/Realm'

Note: pod 'ios-charts' is not the correct library, and refers to a different project by someone else.

Carthage Install

Charts now include Carthage prebuilt binaries.

github "danielgindi/Charts" == 2.2.5
github "danielgindi/Charts" ~> 2.2.5

In order to build the binaries for a new release, use carthage build --no-skip-current && carthage archive Charts && carthage archive ChartsRealm.

3rd party bindings

Xamarin (by @Flash3001): iOS - GitHub/NuGet. Android - GitHub/NuGet.

Documentation

Currently there's no need for documentation for the iOS/tvOS/OSX version, as the API is 95% the same as on Android.
You can read the official MPAndroidChart documentation here: Wiki

Or you can see the ChartsDemo project and learn the how-tos from it.

Special Thanks

Goes to @liuxuan30, @petester42 and @AlBirdie for new features, bugfixes, and lots and lots of involvement in our open-sourced community! You guys are a huge help to all of those coming here with questions and issues, and I couldn't respond to all of those without you.
