报表 charts4j

googlewebjava 
阅读更多
1. 简介
charts4j is a Java chart library that enables developers to programmatically generate nearly all 1 the charts available in the Google Chart API . charts4j can be incorporated into any Internet enabled Java (e.g. Swing) or web application environment (e.g. JSPs / Servlets, Spring MVC, GWT, etc.)

Installation

Developers only need to include the charts4j.jar in their classpath. It is available in the charts4j.zip file. The application must also be connected to the Internet because the charts are ultimately rendered by the Google Chart API server
(上面copy于charts4j 1.3API)

Features
Supports many features of the Google Chart Tools
Hides the ugly details of creating the URL parameters that are necessary for communicating with the Google Chart Tools
Can be incorporated into any Internet enabled Swing or web application environment (JSP/Servlet, GWT, Spring MVC, etc.)
100% pure core Java solution. No need for special graphics libraries, etc.
Super-scalable & Lightweight. Only one 160Kb jar and an Internet connection required
Well documented
GWT client-side support.
JFreeChart Eastwood Servlet integration.
Works on Android
Best of all, it is FREE!
(上面来至官网).
