I have attached a sample chart. I want to update series 1, series 2, series 3 to another value for e.g. I want to update series 1 to ABC.

Thanks

@aliyasserkhan,
Names of the series are stored in chart data (Excel workbook) just like any other data. You can change them in two ways for cells.

Updating through ChartDataWorkbook:

chart.ChartData.ChartDataWorkbook.GetCell(0, 0, 1).Value = "New Series Name 1";

Updating through Series collection:

chart.ChartData.Series[0].Name.AsCells[0].Value = "New Series Name 2";
