## ChartDataLabelCollection::get_Format method


Provides access to fill and line formatting of the data labels.

```cpp
System::SharedPtr<Aspose::Words::Drawing::Charts::ChartFormat> Aspose::Words::Drawing::Charts::ChartDataLabelCollection::get_Format()
```


## Examples



Shows how to set fill, stroke and callout formatting for chart data labels. 
```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::Column, static_cast<double>(432), static_cast<double>(252));
System::SharedPtr<Aspose::Words::Drawing::Charts::Chart> chart = shape->get_Chart();

// Delete default generated series.
chart->get_Series()->Clear();

// Add new series.
System::SharedPtr<Aspose::Words::Drawing::Charts::ChartSeries> series = chart->get_Series()->Add(u"AW Series 1", System::MakeArray<System::String>({u"AW Category 1", u"AW Category 2", u"AW Category 3", u"AW Category 4"}), System::MakeArray<double>({100, 200, 300, 400}));

// Show data labels.
series->set_HasDataLabels(true);
series->get_DataLabels()->set_ShowValue(true);

// Format data labels as callouts.
System::SharedPtr<Aspose::Words::Drawing::Charts::ChartFormat> format = series->get_DataLabels()->get_Format();
format->set_ShapeType(ChartShapeType::WedgeRectCallout);
format->get_Stroke()->set_Color(System::Drawing::Color::get_DarkGreen());
format->get_Fill()->Solid(System::Drawing::Color::get_Green());
series->get_DataLabels()->get_Font()->set_Color(System::Drawing::Color::get_Yellow());

// Change fill and stroke of an individual data label.
System::SharedPtr<Aspose::Words::Drawing::Charts::ChartFormat> labelFormat = series->get_DataLabels()->idx_get(0)->get_Format();
labelFormat->get_Stroke()->set_Color(System::Drawing::Color::get_DarkBlue());
labelFormat->get_Fill()->Solid(System::Drawing::Color::get_Blue());

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