WEB页面下的通用动态数据图表实现技术

Universal Chart Generation Method on Web Pages

MIS系统的开发正在由C/S模式向B/S模式迁移。数据的可视化在MIS应用系统中起着重要作用。人们利用商业数据图表控件来实现MIS系统数据图表 ,例如微软公司的MSCHRT2 0 OCX ,但在基于B/S模式的WEB页面上 ,该控件的一些传递数据的重要属性和方法不起作用。笔者从实际应用的角度介绍了如何在基于B/S模式的WEB页面下动态地获取数据 ,并将获得的数据向该控件传递 ,实现动态数据图表的方法。利用该方法可以自动生成各种数据图表 ,例如统计图形等。

The development mode of MIS application program is transferring from C/S mode to B/S mode.The visualization of data will paly an important role in MIS application program.Many commercial data chart activex controls are used to realize the data chart,such as Microsoft activeX control MSCHRT20.OCX,but some important properties and methods of this control are disabled on WEB pages based on B/S mode.In practical application point of view,a universal chart generation method on web pages is presented in this paper.All kinds of complicated data chart such as statistical chart can be easily be processed to show on web pages by using this method.The detailed implementing steps are also given in this paper.
