说明：  各种工业测控系统中,通常利用动态实时数据 曲线,实时监测某点在现场工况变化下的控制稳定 性。而动态实时数据曲线的实现,就成为测控软件 开发中的一个重要环节。目前,由于VB 具有功能 强大和用户界面易实现等优点,已经成为流行的测 控软件开发工具之一,但同其它编程工具一样,VB 也不具备直接的动态曲线绘制能力,必须借助一些 编程技术来实现。本文详细介绍利用Visual Basic 编程,绘制动态实时数据曲线的方法。
(A variety of industrial measurement and control systems, usually make use of dynamic real-time data curve, real-time monitoring of a point change in working conditions at the scene under the control of stability. Dynamic real-time data curve and the realization of monitoring and control software development has become an important link. At present, because VB has a powerful and user interface easy to realize the advantages of monitoring and control has become a popular software development tools, but as with other programming tools, VB does not have the direct ability of the dynamic curve drawing, we must use some programming technology to realize. This paper describes the use of Visual Basic programming, rendering dynamic real-time data curve method.)
