What is GraphView

GraphView is a library for Android to programmatically create flexible and nice-looking diagrams. It is easy to understand, to integrate and to customize.

Supported graph types:

Line Graphs
Bar Graphs
Point Graphs
or implement your own custom types.

Top Features

Line Chart, Bar Chart, Points
Combination of different graph types
Scrolling vertical and horizontal . You can scroll with a finger touch move gesture.
Scaling / Zooming vertical and horizontal . With two-fingers touch scale gesture (Multi-touch), the viewport can be changed.
Realtime Graph (Live change of data)
Second scale axis
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.
Show legend . A legend can be displayed inline the chart. You can set the width and the vertical align (top, middle, bottom).
Custom labels . The labels for the x- and y-axis are generated automatically. But you can set your own labels, Strings are possible.
Handle incomplete data . It's possible to give the data in different frequency.
Viewport . You can limit the viewport so that only a part of the data will be displayed.
Manual Y axis limits

        android:id="@+id/graph" />

3) 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),
