RCP项目应用jfree实现图形报表中的柱状图与曲线图
RCP项目使用jfree实现图形报表中的柱状图与曲线图
此案例摘取自工作中的功能案例,简单使用不需要进行如果封装数据.如参数类.
RCP项目使用jfree实现图形报表中的柱状图与曲线图.
结构说明:
1. JfreechartUtil.java 实现生成图表数据及生成图表.
2. PlotTempDialog.java 图表显示窗体.
3. PlotParameterVO.java 图表参数类.
4. PlotData.java 封装从显示的数据,从数据库获得
5. 需要相关的JAR文件支持,于附件.
执行PlotTempDialog类的main入口测试.
