Graph View 是一个灵活，美观的android 图表库，现在只有折线图和条形图两种图表样式，易于使用，整合和定制。可以使用在android 1.6以上的版本。

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.
Custom Style
