2D科学数据可视化处理的研究

2D Scientific Data Visualization Processing Research

该文描述了数据可视化处理算法及系统的总体设计与实现技术,详细地论述了系统的图表坐标系算法、屏幕坐标与实际值之间的转换算法、各种图形和图表的实现算法、自动标识等功能的具体实现及其应用,并对系统的整体功能进行了全面的阐述。该文利用面向对象的设计思想设计出了一个比较完整的数据可视化的流程,使得系统具有较好的实用性和可扩展性,所实现的类库可供用户直接使用,也可在其基础上作进一步的开发和完善。

This paper described the algorithm of 2D scientific data visualization processing, the architecture's design of the whole system and its implement technology, It discoursed upon some algorithms and functions in detail, including: algorithms like the algorithm of plot axis, transfers between screen coordinate and axis coordinate, implements of these plots and charts, auto-mark, it expatiated comprehensively the whole functions of the system. A integrated data visualization program is designed with Object Oriented Programming in this paper, which made the system more practical and extendable, and you can directly use the library anywhere. You can also extend and perfect our package as you wish.
