The following code illustrates adding chart labels to the scatter points of the chart.
using (ExcelEngine excelEngine = new ExcelEngine())
{
IApplication application = excelEngine.Excel;

//Get the chart from the charts collection
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;
workbook.SaveAs("ChartLabels.xlsx");
