How can I add a series with a different chart type to my chart?

Here's how you do...

ExcelChart chart = worksheet.Drawings.AddChart("chtLine", eChartType.LineMarkers);        
var serie1= chart.Series.Add(Worksheet.Cells["B1:B4"],Worksheet.Cells["A1:A4"]);
//Now for the second chart type we use the chart.PlotArea.ChartTypes collection...
var chartType2 = chart.PlotArea.ChartTypes.Add(eChartType.ColumnClustered);
var serie2 = chartType2.Series.Add(Worksheet.Cells["C1:C4"],Worksheet.Cells["A1:A4"]);

Answer 2

You can do it like this...

var chartType2 = chart.PlotArea.ChartTypes.Add(eChartType.ColumnClustered)as ExcelBarChart;
(ExcelBarChartSerie) serie2 = (ExcelBarChartSerie) chartType2.Series.Add(Worksheet.Cells["C1:C4"],Worksheet.Cells["A1:A4"]);
serie2.DataLabel.ShowValue = true;
