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
• Realtime Graph (Live)
• And more
