针对目前商用图形软件在实际应用中存在的问题，提出了一种实用而强大的绘图软件设计方法。该设计方法的主要思想是把一幅图形分为背景图形和动态图形，其中动态图形又分为常用图形部分和专用符号图形。对不同图形分别用不同方法实现了绘制、编辑、放缩等功能。利用该设计方法开发了相应的软件，该开发软件还具有图形漫游、数据信息输入等功能。“,”This paper presents a practical and powerful design method. The main idea is that a graph is composed of background and dynamic graph, and the dynamic graph consists of graph in common use and special sign. It uses different methods in drawing, editting, zooming different graph, the software also implements graphic navigation, input of data and so on.
