Abstract

Web-Based applications have penetrated into our business from all walks of life work. In the state of data visualization, dynamic web development technology can facilitate the realization of database queries. The query results are in the browser-side in the appropriate report format. However, because of complexities in the information, it is very difficult to show statistical regularities. Therefore, intuitively in the statistical characteristics of information is the main concern in the joint venture business projects which is addressed in the current project.

In this paper, Web-Based information is iconified by using Ext JS framework. To explain the process, the first part of the paper describes the importance of access to useful information and the establishment of system design based on the necessity and feasibility of the statistical information in the Web icon. And then we introduce the statistic icon systems’ development methods and implementation technologies. The final part presents some examples of the development of Web-Based statistic icons by extracting data from the database and generating radar chart, pie chart, line chart, and bar chart, etc. Also, it successfully visualizes the uncertainty calculation data according to meet the requirements of displaying and analyzing the result of uncertainty calculations.
