CR 10 creating charts

I am using Visual Studio 2005 VB.NET and Crystal Reports 10. I need to create a line graph on a crystal report by sending it a dataset from the vb.net page. I am new to this. Does anyone have any example code or know of any websites that demonstrate how to do this?Please see here (http://www.dev-archive.com/forum/showthread.php?t=409951)
