一种基于JFree Chart的Web统计图表

A Kind of Web Statistic Chart Based on JFreeChart

互联网技术的飞速发展使得基于Web的应用越来越普遍,同时也更加复杂。基于Web的动态统计图表就是一个典型的实例。随着开发技术的不断发展,一些开源项目凭借其公开、自由以及免费等众多优势产生了越来越大的影响,很多项目都采用了开源技术。文中介绍了一种开源的基于Java的报表开发组件JFreeChart引擎,阐述了其图表显示原理。基于JSP和JavaBean技术的B/S开发模式已经成了目前开发基于Java技术的Web应用系统的主导,文章通过在Web上实现动态统计图表,给出了一种典型的应用,并结合一个实际项目中的例子进行了分析,探索出了一种开发Web动态报表的方法。

With the development of Internet,Web application has been more popular and complicated.Dynamic Web statistic chart is a typical case.With the development of developing technology,some open source projects become more infective for open and free,and are implemented in many projects. This paper introduces a kind of open source implementing dynamic statistic chart on Web based on JFreeChart engine,describes the display theory of JFreeChart.The B/S developing pattern based on JSP and Java Bean has been the major technology of Java Web applications nowadays.This paper gives a typical application,analyses with an example in a practical project and finds a way to develop dynamic Web statistic chart.
