轻量级Web表现层Chart的应用

Application of lightweight Web presentation layer Chart

基于服务器/浏览器架构的测控应用越来越多,其中数学表现和信号分析Chart图形需要提供动态的交互反馈和高精度的图像。比较了传统的客户端/服务器(C/S)应用和常见的浏览器/服务器(B/S)应用中Chart图形的实现策略,提出了在ExtJS轻量级框架下结合Emprise Charts控件,利用AJAX技术解决分析信号数据交换的局部刷新,利用JavaS-cript技术,在表现层实现信号分析测控的应用。

More and more applications based on the architecture of Server/Browser for measurement and control, in which mathematics performance and signal analysis Chart graphics need to provide a dynamic and interactive feedback and high-precision images. Compares the implementation strategy of Chart graph in the traditional C/S applications and a common B/S application. ExtJS lightweight framework combined with Emprise Charts control have been proposed, while AJAX technique is adopted to solve the locally refreshing problem of data exchange of analysis signals and the application of signal analysis and control is enabled in the presentation layer by use of JavaSeript technology.
