摘　　要：针对动web图表显示问题，介绍了优秀的绘图组件JFreecharc，结合电缆运行监控与管理系统，具体阐述利用该组件实现了电缆结点温度值的圆柱图、实时线路电流曲线图及历史数据的曲线图等，由于该组件强大图表显示功能，不但减少了开发图形时间而且提高了开发的质量。Aiming at the problem of dynamic web charts, the excellent mapping component is presented. The cable operation monitoring and management system is used as an example, specifically describes this component is adopted to realize some examples, such as cable junction temperature Cylinder diagram, tkeal-dme wire electricity curve, historical data curve and so on. As the components with powerful graphic capabilities, which not only reduce development graphic time and improve the quality of development.
