在Web应用开发中,常需从数据库中提取数据并表示成各种图表。在实际开发中,要想将数据库中的数据在Web页面中以图表的形式呈现,必须通过复杂的代码才能实现。本文设计了基于OWC的Web通用图表分析控件,可以通过ASP.NET直接调用,实现了人们对数据的查询需要以图表方式呈现的要求,并使开发难度和工作量大大减少。
In Web application development, often need to extract data from the database and expressed as a variety of charts. In the actual development, in order to data in the database in the Web page in the form of a graphical presentation, you must pass complex code to achieve. This paper designs a Web-based common chart analysis control based on OWC, which can be directly called by ASP.NET to realize the requirement that people need to present the data in the form of chart, and make the development difficulty and workload greatly reduced.
