Methods
| Method | Description |
|---|---|
| Axis(Axis_Impl* impl) | Constructs from an implementation object. |
| Axis(const Axis& src) | Copy constructor. |
| GetArea() | Gets the Area. |
| GetAxisBetweenCategories() | Represents if the value axis crosses the category axis between categories. |
| GetAxisLine() | Gets the appearance of an Axis. |
| GetAxisTexts() | Gets the labels of the axis after call Chart.Calculate() method. |

| IsDisplayUnitLabelShown() | Represents if the display unit label is shown on the specified axis. |
| IsLogarithmic() | Represents if the value axis scale type is logarithmic or not. |
| IsNull() const | Checks whether the implementation object is nullptr. |
| IsPlotOrderReversed() | Represents if Microsoft Excel plots data points from last to first. |

| SetCustomUnit(int32_t value) | Specifies a custom value for the display unit. |
| SetDisplayUnit(DisplayUnitType value) | Represents the unit label for the specified axis. |
| SetHasMultiLevelLabels(bool value) | Indicates whether the labels shall be shown as multi level. |
| SetIsAutomaticMajorUnit(bool value) | Indicates whether the major unit of the axis is automatically assigned. |

Examples
Aspose::Cells::Startup();
//Instantiating a Workbook object
Workbook workbook;
//Adding a new worksheet to the Excel object
int sheetIndex = workbook.GetWorksheets().Add();
//Obtaining the reference of the newly added worksheet by passing its sheet index
Worksheet worksheet = workbook.GetWorksheets().Get(sheetIndex);
//Adding a sample value to "A1" cell
worksheet.GetCells().Get(u"A1").PutValue(50);
//Adding a sample value to "A2" cell
worksheet.GetCells().Get(u"A2").PutValue(100);
//Adding a sample value to "A3" cell
worksheet.GetCells().Get(u"A3").PutValue(150);
//Adding a sample value to "B1" cell
worksheet.GetCells().Get(u"B1").PutValue(4);
//Adding a sample value to "B2" cell
worksheet.GetCells().Get(u"B2").PutValue(20);
//Adding a sample value to "B3" cell
worksheet.GetCells().Get(u"B3").PutValue(50);
//Adding a chart to the worksheet
int chartIndex = worksheet.GetCharts().Add(ChartType::Column, 5, 0, 25, 5);
//Accessing the instance of the newly added chart
Chart chart = worksheet.GetCharts().Get(chartIndex);
//Adding NSeries (chart data source) to the chart ranging from "A1" cell to "B3"
chart.GetNSeries().Add(u"A1:B3", true);
//Set the major unit
chart.GetValueAxis().SetMajorUnit(25);
//Category(X) axis crosses at the maxinum value.
chart.GetValueAxis().SetCrossType(CrossType::Maximum);
//Set he number of categories or series between tick-mark labels.
chart.GetCategoryAxis().SetTickLabelSpacing(2);
//Saving the Excel file
workbook.Save(u"book1.xlsx");
