• Different plotting types
  Line Chart, Bar Chart and Points Chart and they can be plotted together as a combination.

• Draw multiple series of data
  Let the diagram show more that one series in a graph. You can set a color and a description for every series.

• Realtime / Live Chart
  Append new data live or reset the whole data.

• Secondary Scale

• Tap Listener
  Handle tap events on specific data points.

• Show legend
  A legend can be displayed inline the chart. You can set the width and the vertical align (top, middle, bottom).

• Custom label formatter
  The labels for the x- and y-axis are generated automatically. But you can set your own labels, Strings are possible.

• Handle incomplete data

  Set vertical and horizontal axis titles.

• Many Styles
  change the color and thickness, label font size/color and more.

• Very customizable
  There are many hooks to use in order to do custom rendering or changing the paint objects.

Lets move to implementation of GraphView

Add gradle dependency:

compile 'com.jjoe64:graphview:4.2.1'

Add view to layout:

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

Add some data:

GraphView graph = (GraphView) findViewById(R.id.graph);
LineGraphSeries<DataPoint> series = new LineGraphSeries<DataPoint>(new DataPoint[] {
          new DataPoint(0, 1),
          new DataPoint(1, 5),
          new DataPoint(2, 3),
          new DataPoint(3, 2),
          new DataPoint(4, 6)
});
graph.addSeries(series);
