摘　　要：针对远程数据监测系统中历史曲线显示的需要,介绍了基于Web的远程监测系统中历史曲线的显示机制,通过Nplot控件实现了多条历史曲线的显示。主要介绍了数据库服务器和显示控件两部分,开发出的曲线显示控件(Nplot)可以嵌入到任何Web页面中,通过系统的良好运行情况,证明本系统是成熟可靠的。Aimed at the need of display of history curves in long-distance data monitoring system, this paper introduces the display mechanism of history curves in long-distance monitoring system based on web and realizes the display of many history curves by Nplot, mainly introducing the database-server and the ActiveX data-display, and the curve display control can be embedded into any Web page. The maturity and credibility of the system has been proved by its smooth operation.
