[操作系统]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。
