        {
            //Create worksheet
            IApplication application = excelEngine.Excel;
            application.DefaultVersion = ExcelVersion.Excel2013;
            IWorkbook workbook = application.Workbooks.Create(1);
            IWorksheet sheet = workbook.Worksheets[0];

            //Add data
            sheet.Range["A1"].Text = "Jan";
            sheet.Range["B1"].Text = "Feb";
            sheet.Range["C1"].Text = "Mar";
            sheet.Range["A2"].Value = "10";
            sheet.Range["B2"].Value = "20";
            sheet.Range["C2"].Value = "30";

            //Create chart
            IChart chart = sheet.Charts.Add();

            //Set serie
            IChartSerie serie = chart.Series[0];

            //Set data labels value visibility             
            serie.DataPoints.DefaultDataPoint.DataLabels.IsValue = true;

            //Save and Dispose

The following code illustrates how a particular IChartDataPoint can be accessed from IChartDataPoints collection.

        using (ExcelEngine excelEngine = new ExcelEngine())
        {
            //Create worksheet
            IApplication application = excelEngine.Excel;
            application.DefaultVersion = ExcelVersion.Excel2013;
            IWorkbook workbook = application.Workbooks.Create(1);
            IWorksheet sheet = workbook.Worksheets[0];

            //Add data
            sheet.Range["A1"].Text = "Jan";
            sheet.Range["B1"].Text = "Feb";
            sheet.Range["C1"].Text = "Mar";
            sheet.Range["A2"].Value = "10";
            sheet.Range["B2"].Value = "20";
            sheet.Range["C2"].Value = "30";

            //Create chart
            IChart chart = sheet.Charts.Add();

            //Set range
            chart.DataRange = sheet.Range["A1:C2"];

            //Set serie
            IChartSerie serie = chart.Series[0];

            //Set data labels value visibility             
            serie.DataPoints[0].DataLabels.IsValue = true;

            //Save and Dispose
            workbook.SaveAs("Chart.xlsx");
            workbook.Close();
        }
