A simple chart for Android with three indicators and one more to indicate overall summary. They get highlighted if you click on the ring or text.

Add the gradle dependency to your app module build.gradle file:

dependencies {
    compile 'com.lalongooo:rings:1.0.0'
}

Make sure layout_width and layout_height are equal so rings can be a perfect circle inside a square, otherwise it'd look like an ellipse inside a rectangle.

<com.lalongooo.Rings
    android:id="@+id/rings"
    android:layout_width="200dp"
    android:layout_height="200dp" />
