### Examples

```csharp
namespace AsposeCellsExamples
{
    using Aspose.Cells;
    using Aspose.Cells.Charts;
    using Aspose.Cells.Drawing;
    using System;
    using System.Drawing;

    public class GradientDirectionTypeDemo
    {
        public static void GradientDirectionTypeExample()
        {
            // Create a new workbook
            Workbook workbook = new Workbook();

            // Add a new worksheet to the workbook
            Worksheet worksheet = workbook.Worksheets[0];

            // Add sample data to the worksheet
            worksheet.Cells["A1"].PutValue("Category");
            worksheet.Cells["A2"].PutValue("A");
            worksheet.Cells["A3"].PutValue("B");
            worksheet.Cells["A4"].PutValue("C");

            worksheet.Cells["B1"].PutValue("Value");
            worksheet.Cells["B2"].PutValue(10);
            worksheet.Cells["B3"].PutValue(20);
            worksheet.Cells["B4"].PutValue(30);

            // Add a chart to the worksheet
            int chartIndex = worksheet.Charts.Add(ChartType.Column, 5, 0, 15, 5);
            Chart chart = worksheet.Charts[chartIndex];

            // Set the chart data range
            chart.SetChartDataRange("A1:B4", true);

            // Access the chart's plot area
            PlotArea plotArea = chart.PlotArea;

            // Access the fill format of the plot area
            FillFormat fillFormat = plotArea.Area.FillFormat;

            // Set a two-color gradient fill with a specific direction
            fillFormat.SetTwoColorGradient(Color.Blue, Color.LightBlue, GradientStyleType.DiagonalDown, 1);
            fillFormat.GradientFill.SetGradient(GradientFillType.Linear, 45, GradientDirectionType.FromUpperLeftCorner);

            // Output the gradient direction type
            Console.WriteLine("Gradient Direction Type: " + fillFormat.GradientFill.DirectionType);

            // Save the workbook
            workbook.Save("GradientDirectionTypeExample.xlsx");
            workbook.Save("GradientDirectionTypeExample.pdf");
        }
    }
