• Android图表类库：WilliamChart

    WilliamChart是基于Views的Android图表类库，帮助开发者在Android应用中实现折线图、柱状图和堆叠柱状图。数值发生变化时图表也会以动画的效果发生变化。

    At the moment it provides:

    • LineChartView

    Demo Screenshot1

    • BarChartView

    Demo Screenshot2

    • StackBarChartView

    Demo Screenshot3

    使用说明： 
    创建一个新的chart需要继承自ChartView的坐标轴，同时实现一些必要的方法。我觉的这些方法足以让你绘制出任何你想要的效果。
