动画图表js（行），逐行动画绘制图表
问题描述：
是否有一种方法可以扩展当前的chart.js，以使动画图形不会对整个图表进行动画处理，而是通过动画（轻松）逐行绘制图表？
Is there a way to extend the current chart.js so that the animation drawing doesn't animate the whole chart, but drawing the chart line by line with animation (ease) ?
答
Nevermind。我通过扩展chart.js并覆盖draw（）函数来实现这一点，以便对行进行动画处理从一个点/点到另一个点/点，直到最后一个点/点。
Nevermind.I've implement it by extending chart.js and override draw() function so that I can animate the line from one dot/point to another until the last dot / point.
