Version 2.1.3, synced to MPAndroidChart #62f192e

alt tag CodeHunt.io

  • Xcode 6.3 / Swift 1.2 (Swift 2.0 for Xcode 7 beta is available currently on the swift-2.0 branch)
  • iOS 7.0 (Drag .swift files to your project)
  • iOS 8.0 (Use as an Embedded Framework)

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, both Android and iOS, 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"

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.

Help

If you like what you see here, and want to support the work being done in this repository, you could:

  • Contribute code, issues and pull requests
  • Let people know this library exists (spread the word!)

Donate (You can buy me a beer, or you can buy me dinner :-)

Note: The author of MPAndroidChart is the reason that this library exists, and is accepting donations on his page. He deserves them!

Questions & Issues

If you are having questions or problems, you should:

  • Make sure you are using the latest version of the library. Check the release-section.
  • Study the Documentation-Wiki
  • Search or open questions on stackoverflow with the ios-charts tag
  • Search known issues for your problem (open and closed)
  • Create new issues (please search known issues before, do not create duplicate issues)

Documentation

Currently there's no need for documentation for the iOS 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 @petester42 (Pierre-Marc Airoldi) for implementing a Bubble chart!
To @AlBirdie for his contributions and his involvement in our small community!
And of course thanks to all of those contibuting small fixes here and there! You are all appreciated!
