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

• BarChartView

• StackBarChartView

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。

动画

?

1 2 3 4 5 6 7 8 9 10 11 12

Animation anim = new Animation() anim.setDuration(integer) anim.setEasing(easingFunction) anim.setEndAction(runnable) // Animation overlap between entries anim.setOverlap(float) // Animation starting point anim.setStartPoint(float, float) // Include alpha transition anim.setAlpha(int) // Starts animation chart.animate(animation)
