The following code illustrates adding chart labels to the scatter points of the chart.

using (ExcelEngine excelEngine = new ExcelEngine())

    //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");
