![Release](https://img.shields.io/github/release/PhilJay/MPAndroidChart-Realm.svg?label=maven central)

This repository contains all Realm.io related features of the MPAndroidChart library based on Realm v2.0.2 release.

Getting Started

To use this library, add the following to your project level build.gradle:

allprojects {
  repositories {

maven {
 url "https://jitpack.io" 
}
  
}
 
}

Add this to your app build.gradle:

dependencies {
  compile 'com.github.PhilJay:MPAndroidChart-Realm:v2.0.2@aar'  compile 'com.github.PhilJay:MPAndroidChart:v3.0.2' 
}

The MPAndroidChart-Realm dependency does not include the latest MPAndroidChart release, so you have to add the dependency to MPAndroidChart as well (as shown above). You also have to add the Realm.io dependency.

Sample

Using MPAndroidChart with Realm.io is easier than you think.

// get realm instance Realm realm = Realm.getDefaultInstance();
  // load your data from Realm.io database RealmResults<YourData> results = realm.where(YourData.class).findAll();
  // create a DataSet and specify fields, MPAndroidChart-Realm does the rest RealmBarDataSet<YourData> dataSet = new RealmBarDataSet<YourData>(results, "xValue", "yValue");
  // create a data object with the dataset  BarData data = new BarData(dataSet);
 chart.setData(data);
 chart.invalidate();
 // refresh

Tutorial

Here, you can find a full guide on how to plot data from Realm.io database with MPAndroidChart from scratch.

Decorator

The idea behind the decorator pattern is to decouple responsibilities from the parent class into reusable components. Individual decorators can then be attached to otherwise empty parent classes to do a single job. This allows a simple java class to have multiple and dynamic inheritance. In order to make this pattern scalable with minimal boilerplate, an easy to use code-generation library was created to automate most of its creation.
