摘　　要：传统的Web图表开发在不同终端、不同平台上实现时,为满足用户全方位、多角度的体验而采用不同的图形组件,这无疑增加了开发量与维护量。JFreeChart是Java平台上一个开源图表绘制类库,动态图表在不同终端和平台生成时都基于相同的绘图组件,其提供了基于C/S与B/S架构下生成各种图片格式的图表,具有种类丰富、功能完善的数据图形表现力与渲染力。为使转子动平衡计算结果显示更加清晰、直观,同时增强该Web APP页面的功能与显示效果,结合JFreeChart开源图形包的特点、工作原理及开发流程,基于Vaadin开发框架,设计并实现了转子动平衡计算数据的动态图形显示。实例应用表明,JFreeChart在数据图表实现时,不仅显著提高了开发效率,也兼顾了不同终端的用户体验。Traditional Web chart development in different terminals and different platforms to achieve, in order to meet the user＇s all-round, multi-angle experience and the use of different graphics components, which undoubtedly increased the developer＇s development and maintenance, JFreeChart is an open source drawing class library on the Java platform. Dynamic charts are based on the same drawing components when different terminals and platforms are generated. It provides graphs based on C / S and B / S architectures that generate various picture formats. With a variety of rich and functional data graphics performance and rendering power. This paper combines the characteristics, working principle and development process of JFreeChart open source graphics package, while enhancing the Web APP page features and display based on the Vaadin development framework, designs and realizes dynamic graphic display of dynamic balance calculation data for rotating machinery. Case application shows that JFreeChart in cross-platform cross-terminal development, not only significantly improve the development efficiency, but also take into account the different terminal user experience.
