Calling a C# file in an ASP?

Hello I am new to web development and was wondering if I would be able to call a C# file from an asp file. Or maybe something different then a C# file. I was hoping someone out be able to suggest what to code the graph in order to display it in a web based program. I need to make an enhanced trend graph that will also have bar graphs and scatter plots included in this trend graph.

Thanks

Hi,

Can you clarify something? Are you talking about classic ASP or ASP.NET? There is a big difference. The advice you will get will depend on your answer to this question...

It is classic asp
