    var workbook = Workbook.Create( ChartSample.ChartSampleOutputDirectory + @"AddCharts.xlsx" );
    
    // Gets the first Worksheet. A Workbook always contains at least 1 Worksheet.
    var worksheet = workbook.Worksheets[ 0 ];
    
    // Adds Values for Category.
    worksheet.Cells[ "B4" ].Value = 2020;
    worksheet.Cells[ "B5" ].Value = 2021;
    worksheet.Cells[ "B6" ].Value = 2022;
    worksheet.Cells[ "B7" ].Value = 2023;
    worksheet.Cells[ "B8" ].Value = 2024;
    
    // Adds Values for Series.
    worksheet.Cells[ "C4" ].Value = 20;
    worksheet.Cells[ "C5" ].Value = 28;
    worksheet.Cells[ "C6" ].Value = 33;
    worksheet.Cells[ "C7" ].Value = 12;
    worksheet.Cells[ "C8" ].Value = 45;
    worksheet.Cells[ "D4" ].Value = 7;
    worksheet.Cells[ "D5" ].Value = 33;
    worksheet.Cells[ "D6" ].Value = 15;
    worksheet.Cells[ "D7" ].Value = 35;
    worksheet.Cells[ "D8" ].Value = 25;
    
    // Adds a DoughnutChart with the generic Add method. The size of the Chart will be from Cell E4 to L18.
    var doughnutChart = worksheet.Charts.Add<DoughnutChart>( "E4", "L18" );
    
    // Sets the Chart's Title.
    doughnutChart.Title.Text = "Profits";
    doughnutChart.Title.TextOptions.Font.Bold = true;
    
    // Sets the Legend.
    doughnutChart.Legend.Position = LegendPositionType.Right;
    
    // Sets the Category data(x values) for the DoughnutChart : Cells B4 to B8.
    doughnutChart.CategoryData = CategoryData.FromCells( worksheet, "B4", "B8" );
    
    // Adds DoughnutSeries to the DoughnutChart (y values) by specifying fixed values, a Range of Cells’ Adresses and a Range of Cells’ Row & Column ids.
    var doughnutSeries1 = doughnutChart.SeriesCollection.AddFromValues<DoughnutSeries>( 5, 10, 15, 20, 40 );
    doughnutSeries1.Name = "IBM";
    var doughnutSeries2 = doughnutChart.SeriesCollection.AddFromCells<DoughnutSeries>( "C4", "C8" );
    doughnutSeries2.Name = "Apple";
    var doughnutSeries3 = doughnutChart.SeriesCollection.AddFromCells<DoughnutSeries>( 3, 3, 7, 3 );
    doughnutSeries3.Name = "Amazon";
    
    // Sets the hole size of the Doughnut chart.
    doughnutChart.HoleSize = 42;
    
    // Saves workbook to disk.
    workbook.Save();
