摘　　要：介绍了公交运行计划图,对其基本算法进行了描述,包括坐标系转换算法和运行计划图绘制算法,通过.NET平台进行实现。介绍了运行计划图定义的类,并以一个类为例说明类的属性和方法,详细说明了运行计划图各种操作的实现,包括运行线图元的增加、删除、拖动和线上点位置的移动,以及图形的序列化,并能实现撤销或重做。程序运行结果表明,该运行计划图比表格式运行计划更能满足实际需要。This paper introduced chart in public transportation system and illustrated its basic algorithrns. Which was implemented based on .NET. It illustrated the main classes and implemention of the basic operations, including increasing, drag and trop and canceling of graphic elements as well as serialization, undoing and redoing of graph. The result shows that the running chart is more practical than timetable.
