One of the most apparent ways is using Microsoft Chart Control for ASP.NET:

Hello,

Go through following article:
drawing line chart[^]
Creating Line Chart For WebForms Using C#.[^]

For continuous update you can use Substitution Control, which will help in getting the updated data.
Please go through following article for more information:
http://msdn.microsoft.com/en-us/library/ms228212.aspx[^]
http://www.dotnetfunda.com/tutorials/controls/substitution.aspx[^]

You can also use XMLHTTPRequest, which will hit the database to get the updated data. You can the use the result of XMLHTTPRequest to update the line graph.
