Is this in C#? If so you need to look at Microsoft.Office.Interop.Excel 
- the VS help and google will get you started using it, it's very easy 
to do.

Mind you Excel's graphs are pretty yucky by default (although the newer 
Office versions seem to have improved this).

If you /are/ on C# and using Windows forms then don't forget you've got 
built in DataVisualization.Charting which can be used to quickly add a 
charting capabilities to your program.
