Example:

            [C#]
             Workbook book = new Workbook(); 
             Worksheet sheet = book.Worksheets[0];
            
             sheet.Cells["A1"].PutValue(5);
             sheet.Cells["B1"].PutValue(2);
             sheet.Cells["C1"].PutValue(1);
             sheet.Cells["D1"].PutValue(3);
             
             // Define the CellArea
             CellArea ca = new CellArea();
             ca.StartColumn = 4;
             ca.EndColumn = 4;
             ca.StartRow = 0;
             ca.EndRow = 0;
            
             int idx = sheet.SparklineGroupCollection.Add(Aspose.Cells.Charts.SparklineType.Line, sheet.Name + "!A1:D1", false, ca);
            
             SparklineGroup group = sheet.SparklineGroupCollection[idx];
             idx = group.SparklineCollection.Add(sheet.Name + "!A1:D1", 0, 4);
             Sparkline line = group.SparklineCollection[idx];
             Console.WriteLine($"Saprkline data range:{line.DataRange}, row:{line.Row}, column:{line.Column}");
             line.ToImage("output.png", new ImageOrPrintOptions());
