说明：  介绍了利用Teechart 组件如何实现工业控制领域中的实时曲线和历史曲线,对动态曲线的显示方式进行了讨论,给出了相关代码#并在c++Builder 编程环境下完成了动态数据曲线的实时显示和历史数据曲线的显示.
(How to draw the real_time curve and historical curve in industrial control field using Teechart groupware is presented in this paper.The different display mode of dynamic curve is discussed and correlated code is shown.and the displaying of real_time curve and historical curve are realized under the circumstance of c++Builder.)
