GraphView is a library for Android to programmatically create flexible and nice-looking diagrams. It is easy to understand, to integrate and to customize. Create Line Graphs, Bar Graphs, Point Graphs or implement your own custom types.

XML Layout file:

<com.jjoe64.graphview.GraphView
        android:layout_width="match_parent"
        android:layout_height="200dip"
        android:id="@+id/graph" />

Java code:

GraphView graph = (GraphView) findViewById(R.id.graph);
LineGraphSeries<DataPoint> series = new LineGraphSeries<>(new DataPoint[] {
          new DataPoint(0, 1),
          new DataPoint(1, 5),
          new DataPoint(2, 3)
});
graph.addSeries(series);
