Aspose.Words permite a los usuarios trabajar con ChartDataLabel de varias maneras.

Cómo Formatear la Etiqueta del Número de Datos del Gráfico

Con NumberFormat puede especificar el formato numérico de una sola etiqueta de datos del gráfico.

El siguiente ejemplo de código muestra cómo formatear un número de la etiqueta de datos:

For complete examples and data files, please go to https://github.com/aspose-words/Aspose.Words-for-C
System::SharedPtr<Document> doc = System::MakeObject<Document>();
System::SharedPtr<DocumentBuilder> builder = System::MakeObject<DocumentBuilder>(doc);

// Add chart with default data.
System::SharedPtr<Shape> shape = builder->InsertChart(ChartType::Line, 432, 252);
System::SharedPtr<Chart> chart = shape->get_Chart();
chart->get_Title()->set_Text(u"Data Labels With Different Number Format");

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

// Add new series
System::SharedPtr<ChartSeries> series1 = chart->get_Series()->Add(u"AW Series 1", System::MakeArray<System::String>({u"AW0", u"AW1", u"AW2"}), System::MakeArray<double>({2.5, 1.5, 3.5}));

series1->set_HasDataLabels(true);
series1->get_DataLabels()->set_ShowValue(true);
series1->get_DataLabels()->idx_get(0)->get_NumberFormat()->set_FormatCode(u"\"$\"#,##0.00");
series1->get_DataLabels()->idx_get(1)->get_NumberFormat()->set_FormatCode(u"dd/mm/yyyy");
series1->get_DataLabels()->idx_get(2)->get_NumberFormat()->set_FormatCode(u"0.00%");

// Or you can set format code to be linked to a source cell,
// in this case NumberFormat will be reset to general and inherited from a source cell.
series1->get_DataLabels()->idx_get(2)->get_NumberFormat()->set_IsLinkedToSource(true);

System::String outputPath = outputDataDir + u"ChartNumberFormat.docx";
doc->Save(outputPath);

Cómo Trabajar Con La Etiqueta de Datos Del Gráfico

Con ChartDataLabel puede especificar el formato de una sola etiqueta de datos de la serie de gráficos, como mostrar / ocultar LegendKey, CategoryName, SeriesName, Valor etc:

For complete examples and data files, please go to https://github.com/aspose-words/Aspose.Words-for-C
System::SharedPtr<Document> doc = System::MakeObject<Document>();
System::SharedPtr<DocumentBuilder> builder = System::MakeObject<DocumentBuilder>(doc);

System::SharedPtr<Shape> shape = builder->InsertChart(ChartType::Bar, 432, 252);
System::SharedPtr<Chart> chart = shape->get_Chart();

// Get first series.
System::SharedPtr<ChartSeries> series0 = shape->get_Chart()->get_Series()->idx_get(0);

System::SharedPtr<ChartDataLabelCollection> labels = series0->get_DataLabels();

// Set properties.
labels->set_ShowLegendKey(true);

// By default, when you add data labels to the data points in a pie chart, leader lines are displayed for data labels that are
// Positioned far outside the end of data points. Leader lines create a visual connection between a data label and its
// Corresponding data point.
labels->set_ShowLeaderLines(true);

labels->set_ShowCategoryName(false);
labels->set_ShowPercentage(false);
labels->set_ShowSeriesName(true);
labels->set_ShowValue(true);
labels->set_Separator(u"/");
labels->set_ShowValue(true);

System::String outputPath = outputDataDir + u"SimpleBarChart_out.docx";
doc->Save(outputPath);
