Android chart Class Library: William chart,

William chart is an Android chart class library based on Views. It helps developers implement line charts, bar charts, and Stacked column charts in Android applications. When the value changes, the chart also changes with the animation effect.

At the moment it provides:

• LineChartView

• BarChartView

• StackBarChartView

Instructions for use:
To create a new chart, you must inherit the coordinate axes of the ChartView and implement some necessary methods. I think these methods are enough for you to draw any effect you want.
