在 Excel 图表中，有 3 种轴：

轴选项

Aspose.Cells 还允许在运行时管理图表的轴，使用轴对象，您可以像在 Excel 中一样更改 Axis 的所有选项。

在 Excel 图表中，水平轴和垂直轴是最常用的两个轴。

下面的代码片段演示了如何设置 X 和 Y 轴的选项。


	// Instantiating a Workbook object
	Workbook workbook = new Workbook();

	// Adding a new worksheet to the Workbook 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("Series1");
	worksheet.Cells["A2"].PutValue(50);
	worksheet.Cells["A3"].PutValue(100);
	worksheet.Cells["A4"].PutValue(150);
	worksheet.Cells["B1"].PutValue("Series2");
	worksheet.Cells["B2"].PutValue(60);
	worksheet.Cells["B3"].PutValue(32);
	worksheet.Cells["B4"].PutValue(50);

	// Adding a chart to the worksheet
	int chartIndex = worksheet.Charts.Add(Aspose.Cells.Charts.ChartType.Column, 5, 0, 15, 5);

	// Accessing the instance of the newly added chart
	Aspose.Cells.Charts.Chart chart = worksheet.Charts[chartIndex];
	// Adding SeriesCollection (chart data source) to the chart ranging from "A1" cell to "B3"
	chart.SetChartDataRange("A1:B4",true);

	//hiding X axis
	chart.CategoryAxis.IsVisible = false;

	// Setting max value of Y axis.
	chart.ValueAxis.MaxValue = 200;
	// Setting major unit.
	chart.ValueAxis.MajorUnit = 50;

	// Save the file
	workbook.Save("chart_axes.xlsx");
