### Examples

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

    public class CategoryTypeDemo

            // Adding a new worksheet to the Excel object
            int sheetIndex = workbook.Worksheets.Add();
            // Obtaining the reference of the newly added worksheet by passing its sheet index
            Worksheet worksheet = workbook.Worksheets[sheetIndex];
            // Adding sample values to cells
            worksheet.Cells["A1"].PutValue("Dates");
            worksheet.Cells["A2"].PutValue(new DateOnly(2024, 01, 01));

            // Adding a chart to the worksheet
            int chartIndex = worksheet.Charts.Add(ChartType.Column, 5, 0, 25, 5);
            // Accessing the instance of the newly added chart
            Chart chart = worksheet.Charts[chartIndex];
            // Adding NSeries (chart data source) to the chart ranging from "A1" cell to "B3"
            chart.NSeries.Add("B2:C4", true);

            // Setting the category names for the X-axis from the range "A2:A5"
            chart.NSeries[0].XValues = "A2:A4";

            // Setting the category axis type to TimeScale
            chart.CategoryAxis.CategoryType = CategoryType.CategoryScale;

            // Setting the major unit scale for the category axis
            chart.CategoryAxis.MajorUnitScale = TimeUnit.Months;
            chart.CategoryAxis.MajorUnit = 2;

            // Setting the minor unit scale for the category axis
            chart.CategoryAxis.MinorUnitScale = TimeUnit.Months;
            chart.CategoryAxis.MinorUnit = 2;

            // Saving the Excel file
            workbook.Save("CategoryTypeExample.xlsx");
            workbook.Save("CategoryTypeExample.pdf");

        }
