首先声明本程序不是本人全部原创，改编于一个老外的程序，下面是人家编写此程序的原因，表达对大牛的崇拜之情。原程序是一个动态曲线显示。

Description:
The initial idea of doing this code has been put into my mind when my love asked me
to go to a clinic in order to check out my heart. You know, doctors have got some
sort of plotters that plots the information obtained from the heart on a piece of
paper as a histogram. The idea has been dropped into my mind there!
Dedicated to:
My love, Cindy

源程序效果：
1、下面说明自己开发的需求：
很多同事在工程调试中，包括自己干工程的时候，经常遇到已知现场电压、电流、或者压力、流量曲线(本人电气男)，我们需要去拟合出来和现场差不多的曲线，要拟合肯定得需要原始的点数据，所以特别想要一款工具，能够根据自己随手画的曲线和定义好的坐标，方便的取出曲线上任何一个点。
2、工具应该具备的功能：
能够方便的划出曲线，能够设置横纵坐标，能够方便取点。
3、先给出实现后的效果图：顶部实时动态的显示曲线上任意点的坐标，右击能够清空曲线，设置横纵坐标的范围。这是一个发电机并网大致的升压曲线。
4、源代码

可执行文件下载地址：http://download.csdn.net/detail/dubuzherui/7717989
具体实现步骤：
首先，肯定是绘制坐标：
然后，利用画线记录在客户区；
最后，捕捉鼠标的位置。
具体代码，下个博文再详细写，赶紧下班回去了。
