Just posted script, demos and article for creating AJAX Bar Graph with ASP.NET(2.0). Using my script you can create AJAX Bar Graphs using only HTML and ASP.NET. They can be used to show real time information like cricket scores, stock quotes, temperature or any numeric data streaming form a web server.
Download the code and run it from your local machine. Here is the link http://ashishware.com/AJAXGraph.shtml
I am also working on page that demonstrates how to use the script with any server side programing language. Once it is ready , you will find it on my website !
