坐标曲线的编程实现

在实际应用中经常会要画各种统计图。坐标曲线图是其中比较常用的一种。而坐标曲线在各种统计图中应该算比较难画的，主要是很难将坐标值与图中的位置对应起来。我在做一个asp网站的项目中曾遇到过要画坐标曲线，由于没有易用免费的控件可用，只好自己来实现。因此对画坐标曲线有了一点心得。

-curve coordinates the program in practical applications often want to paint all kinds of statistics and maps. Coordinate curve which is a more commonly used. And coordinate the various statistical curves map should count more difficult paintings, it is very difficult to coordinate and map the location matching. I was doing an asp website project has encountered want to paint coordinates curve, owing to the lack of user-friendly controls available free of charge, but his is to be achieved. Therefore the paintings, there was a slight curve coordinates experience.
