摘　　要：对于一般的本地图片或者网页上的图片,在鼠标移动的时候,并不能显示曲线上点的具体信息和精确坐标值。针对这一情况,利用JavaScript语言编制曲线图网页,当用户鼠标置于曲线上任意点时,可显示出该点具体信息以及对应坐标值。整个网页由C#程序自动生成,无需借助其他控件,并且无论在本地双击或者放在网上都可以顺利实现此项功能。For a common graph or a graph on a web page, when the mouse is moving over the curve, specific information and exact coordinates of the point on the curve could not be displayed. In response to this situation, a web page written by JavaScript will show that specific information, as well as the corresponding coordinates values when user＇s mouse over any point on the curve. This web page gener- ated by C# program automatically, and this function can be accomplished successfully through a local double-click or the Internet.
