In the applications system of Web database,sometimes need some statistical diagram to deliver exact and intuitionistic information.The traditional HTML could append it,but as the limitation of storage form,that couldn't be downloaded fast,and also couldn't be zoomed in or out.Only using the HTML couldn't express the vector graphic very well,and cannot work out the problem above.Using VML can offer a scheme for this problem.Used VML and integrated it with ASP to access the database,and building the client scripts dynamically.In this way,the client could figure out better vector graphics,which is visualized,could be zoomed in and out without affecting the quantity.And indicates that could exert the advantage of ASP adequately.At last,illustrate an example to picture a statistical comparative trend graphic about data item,and it has stronger capability of expression.That indicates sufficiently using VML to protract vector graphics has right smart advantage.
