为满足工业控制等领域对数据进行曲线分析的需要,应用TeeChart控件,对需要实时曲线或历史曲线方式的数据,实现显示、对比等分析功能,并且分析结果可以保存为各种文件形式.给出了VC++软件开发环境下的相关实现代码. -Curve analysis of the data needs to meet in areas such as industrial control, given TeeChart control applications, the need for real-time

VB编写的与PCL下位机通信的程序，主要使用VB的mscomm控件实现，其中还包括实时曲线的绘制-VB, and PCL next crew communication procedures, the main use of VB mscomm control implementation, which also includes real-time curve drawing

用vb的timer控件模拟数据采集，并在picturebox里绘制坐标系和实时数据采集曲线-The timer control with vb analog data acquisition, and draw coordinates and real time data acquisition curve in picturebox
