IChart chart = worksheet.Charts[0];
//Get the first series from the Series collection
IChartSerie serieOne = chart.Series[0];
//Set the Series name to the Data Labels through Data Points
serieOne.DataPoints[0].DataLabels.IsSeriesName = true;
//Set the Value to the Data Labels through Data Points
serieOne.DataPoints[0].DataLabels.IsValue = true;
FileStream stream = new FileStream("ChartLabels.xlsx", FileMode.OpenOrCreate, FileAccess.ReadWrite);
