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).

Features

• Two types: Line and Bar
• Custom labels The labels for the x- and y-axis are generated automatically. But you can set your only labels, Strings are possible.
• Background Optionally draws a light background under the diagramm stroke.
• 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, the viewport can be changed.
