How do I set an Excel Chart Series up using VB.Net

Asked by kuelbsd in .NET, Microsoft Excel Spreadsheet Software, Visual Studio .NET 2005

Tags: Microsoft, vb.net & Excel, vb.net 2005 Excell 2000

I am reading a database and creating several excel spreadsheets containing different view of the data.  I would also like to chart the data.  I have everything formatted out correctly but the series name.  The legend always reads, "series 1, series 2, etc"  I need to be able to assign the names to the series.

The code used to generate the chart is attached and a view of the chart.Start Free Trial
