The Research And Implementation Of SVG-based Data Analysis Chart System

With the popularization and development of network technology, graphics and image technology as the base of WEB browser technology plays an important role. XML-based SVG (Scalable Vector Graphics) as an image format of textualized network vector has the advantages and development prospects which can not be surpassed by other image formats.Base on the studying of SVG display graphics principles and technologies, the thesis analysed and compared the display methods of existing graphics on WEB browser. A system model for developing the SVG-based data analysis chart system is proposed. According to the requirements of system function model, three kinds of data sources (database data, XML data files and EXCEL form documents) have been respectively analyzed and processed, and the drawing of vector charts and the output of SVG formats have been achieved. Finally, a summary of the thedsis is made, accompanied by putting forward the further research direction.The new system can help users overcome the difficulties of directly using SVG. Under this system, professional-level charts can be drawn with the help of chart template libraries. As well, the system is characterized by the Heterogeneous platform, extensible and reusable advantages, expansion of different chart template libraries, and high adaptability to different needs of users. The system can help achieve the goal of dynamically generating real-time charts, and speed up the process of releasing the real-time information.
