You can create a sparkline from a named range with the help of the following code.

using (ExcelEngine excelEngine = new ExcelEngine())
{
    IApplication application = excelEngine.Excel;
    application.DefaultVersion = ExcelVersion.Excel2016;
    IWorkbook workbook = application.Workbooks.Create(1);
    IWorksheet worksheet = workbook.Worksheets[0];

    //Add sample data
    worksheet["A1"].Number = 6911;
    worksheet["B1"].Number = 8261;
    worksheet["C1"].Number = 812;
    worksheet["D1"].Number = 166;

    //Add SparklineGroups
    ISparklineGroup sparklineGroup = worksheet.SparklineGroups.Add();

    //Add SparkLineType
    sparklineGroup.SparklineType = SparklineType.Line;
    sparklineGroup.MarkersColor = Color.BlueViolet;

    //Add sparklines
    ISparklines sparklines = sparklineGroup.Add();

    //Create named ranges
    IName name1 = workbook.Names.Add("Data_Range");
    name1.RefersToRange = worksheet.Range["A1:D1"];
    IRange dataRange = worksheet.Range["Data_Range"];

    IName name2 = workbook.Names.Add("Sparkline_Range");
    name2.RefersToRange = worksheet.Range["E1"];                
    IRange referenceRange = worksheet.Range["Sparkline_Range"];

    //Add a sparkline
    sparklines.Add(dataRange, referenceRange);

    workbook.SaveAs("SparklineFromNamedRange.xlsx");
