Utilisation de l'étiquette de données de graphique

Aspose.Words permet aux utilisateurs de travailler avec ChartDataLabel de différentes manières.

Comment Formater le Nombre d’étiquettes de données de graphique

En utilisant NumberFormat, vous pouvez spécifier le formatage des nombres d’une seule étiquette de données du graphique.

L’exemple de code suivant montre comment formater un certain nombre d’étiquettes de données:

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);

Comment Travailler Avec L’Étiquette de Données de Graphique

En utilisant ChartDataLabel, vous pouvez spécifier le formatage d’une seule étiquette de données de la série de graphiques, comme afficher / masquer LegendKey, CategoryName, SeriesName, Valeur 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);
