This repository contains all Realm.io related features of the MPAndroidChart library based on Realm v4.2.0 release.

• 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 {
	implementation 'com.github.PhilJay:MPAndroidChart-Realm:v3.0.3@aar'
	implementation 'com.github.PhilJay:MPAndroidChart:v3.0.3'
}

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.

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

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