## AxisDisplayUnit class


Provides access to the scaling options of the display units for the value axis. To learn more, visit the [Working with Charts](https://docs.aspose.com/words/cpp/working-with-charts/) documentation article.

```cpp
class AxisDisplayUnit : public Core::IDmlChartTitleHolder,
                        public Aspose::Words::Drawing::Core::Dml::IDmlExtensionListSource
```

## Methods

| [get_Document](./get_document/)() | Returns the document containing the parent chart. |
| [get_Unit](./get_unit/)() const | Gets or sets the scaling value of the display units as one of the predefined values. |
| [GetType](./gettype/)() const override |  |
| [Is](./is/)(const System::TypeInfo\&) const override |  |
| [set_CustomUnit](./set_customunit/)(double) | Setter for [Aspose::Words::Drawing::Charts::AxisDisplayUnit::get_CustomUnit](./get_customunit/). |
| [set_Unit](./set_unit/)(Aspose::Words::Drawing::Charts::AxisBuiltInUnit) | Setter for [Aspose::Words::Drawing::Charts::AxisDisplayUnit::get_Unit](./get_unit/). |
| static [Type](./type/)() |  |

## Examples



Shows how to manipulate the tick marks and displayed values of a chart axis. 
```cpp
auto doc = System::MakeObject<Aspose::Words::Document>();
auto builder = System::MakeObject<Aspose::Words::DocumentBuilder>(doc);

System::SharedPtr<Aspose::Words::Drawing::Shape> shape = builder->InsertChart(ChartType::Scatter, static_cast<double>(450), static_cast<double>(250));
System::SharedPtr<Aspose::Words::Drawing::Charts::Chart> chart = shape->get_Chart();

ASSERT_EQ(1, chart->get_Series()->get_Count());
ASSERT_EQ(u"Y-Values", chart->get_Series()->idx_get(0)->get_Name());

// Set the minor tick marks of the Y-axis to point away from the plot area,
// and the major tick marks to cross the axis.
System::SharedPtr<Aspose::Words::Drawing::Charts::ChartAxis> axis = chart->get_AxisY();
axis->set_MajorTickMark(AxisTickMark::Cross);
axis->set_MinorTickMark(AxisTickMark::Outside);

// Set they Y-axis to show a major tick every 10 units, and a minor tick every 1 unit.
axis->set_MajorUnit(10);
axis->set_MinorUnit(1);

// Set the Y-axis bounds to -10 and 20.
// This Y-axis will now display 4 major tick marks and 27 minor tick marks.
axis->get_Scaling()->set_Minimum(System::MakeObject<Aspose::Words::Drawing::Charts::AxisBound>(static_cast<double>(-10)));
axis->get_Scaling()->set_Maximum(System::MakeObject<Aspose::Words::Drawing::Charts::AxisBound>(static_cast<double>(20)));

// For the X-axis, set the major tick marks at every 10 units,
// every minor tick mark at 2.5 units.
axis = chart->get_AxisX();
axis->set_MajorUnit(10);
axis->set_MinorUnit(2.5);

// Configure both types of tick marks to appear inside the graph plot area.
axis->set_MajorTickMark(AxisTickMark::Inside);
axis->set_MinorTickMark(AxisTickMark::Inside);

// Set the X-axis bounds so that the X-axis spans 5 major tick marks and 12 minor tick marks.
axis->get_Scaling()->set_Minimum(System::MakeObject<Aspose::Words::Drawing::Charts::AxisBound>(static_cast<double>(-10)));
axis->get_Scaling()->set_Maximum(System::MakeObject<Aspose::Words::Drawing::Charts::AxisBound>(static_cast<double>(30)));
axis->get_TickLabels()->set_Alignment(ParagraphAlignment::Right);

ASSERT_EQ(1, axis->get_TickLabels()->get_Spacing());
ASPOSE_ASSERT_EQ(doc, axis->get_DisplayUnit()->get_Document());

// Set the tick labels to display their value in millions.
axis->get_DisplayUnit()->set_Unit(AxisBuiltInUnit::Millions);

// We can set a more specific value by which tick labels will display their values.
// This statement is equivalent to the one above.
axis->get_DisplayUnit()->set_CustomUnit(1000000);

doc->Save(get_ArtifactsDir() + u"Charts.AxisDisplayUnit.docx");
