Chart and Graph Library for Android

What is GraphView

GraphView is a library for Android to programmatically create flexible and nice-looking diagramms. It is easy to understand, to integrate and to customize it. At the moment there are two different types:

Line Charts
Bar Charts

Tested on Android 1.6, 2.2, 2.3 and 3.0 (honeycomb, tablet), 4.0.

Features

Two chart types Line Chart and Bar Chart.
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.
Scrolling You can scroll with a finger touch move gesture.
Scaling / Zooming Since Android 2.3! With two-fingers touch scale gesture (Multi-touch), the viewport can be changed.
Background (line graph) Optionally draws a light background under the diagram stroke.
Manual Y axis limits

Very simple example:

// init example series data
GraphViewSeries exampleSeries = new GraphViewSeries(new GraphViewData[] {
	      new GraphViewData(1, 2.0d)
	      , new GraphViewData(2, 1.5d)
	      , new GraphViewData(3, 2.5d)
	      , new GraphViewData(4, 1.0d)
});

GraphView graphView = new LineGraphView(
      this // context
      , "GraphViewDemo" // heading
);
graphView.addSeries(exampleSeries); // data

LinearLayout layout = (LinearLayout) findViewById(R.id.layout);
layout.addView(graphView);
