JCLineChartView

参考几个画曲线图代码,然后综合起来写的一个曲线视图。

================================================================

已实现:

1、能够类似PNChart在一个view上画多条曲线。

2、曲线通过Catmull-Rom样条插值实现,曲线趋势由 前两点 + 当前点 + 后一点 形成插值点。

3、多点间可插入值为 CGFLOAT_MIN 的点,使曲线断开。

4、支持环形曲线区域内填充颜色。

5、支持输入两条曲线,对两条曲线内区域填充颜色。

================================================================

Demo中的使用例子:

1、同时画多条曲线。

2、画中间有断点的线。

3、用颜色填充曲线内部区域。

4、用颜色填充曲线内部区域,且画边框。

5、输入两条曲线,对两条曲线间的区域进行颜色填充。

================================================================

可与JCAdsorbScrollView配合使用,使滚动结束时自动吸附到曲线的点上。例子如下:
