利用JFreeChart在JSP中制作图表

Generating charts in JSP by using JFreeChart

图表的应用不但可以使数据的显示更加清晰、直观,而且可大大增强Web页面的功能和显示效果。针对目前实际应用中经常需要通过数据库中的数据生成相应的图表这一强大需求,介绍了JFreeChart中通过其提供的数据集合对象在JSP页面中生成图表的方法,并给出了生成饼图和柱状图的具体方法和代码。

Using charts can not only make data be clearer, more intuitive, but also greatly enhance the Web page and display effects. Aiming at the strong request to generate corresponding charts through data in database in practical applications, a method to generate charts in JSP pages through the data set object supplied by JFreeChart is introduced. The concrete realization method and code of the pie chart and histogram are given.
