Créer des graphiques OOXML à partir de zéro

Création de graphiques OOXML à partir de zéro en utilisant Aspose.Words

Aspose.Words fournit la méthode InsertChart qui a été ajoutée à la classe DocumentBuilder. Voyons donc comment insérer un simple histogramme dans le document en utilisant la méthode DocumentBuilder->InsertChart:

Comment insérer un graphique à colonnes

L’exemple de code ci - dessous montre comment insérer un histogramme.

System::SharedPtr<Document> doc = System::MakeObject<Document>();
System::SharedPtr<DocumentBuilder> builder = System::MakeObject<DocumentBuilder>(doc);

// Add chart with default data. You can specify different chart types and sizes.
System::SharedPtr<Shape> shape = builder->InsertChart(ChartType::Column, 432, 252);

// Chart property of Shape contains all chart related options.
System::SharedPtr<Chart> chart = shape->get_Chart();

// Get chart series collection.
System::SharedPtr<ChartSeriesCollection> seriesColl = chart->get_Series();
// Check series count.
std::cout << seriesColl->get_Count() << std::endl;

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

// Create category names array, in this example we have two categories.
System::ArrayPtr<System::String> categories = System::MakeArray<System::String>({u"AW Category 1", u"AW Category 2"});

// Adding new series. Please note, data arrays must not be empty and arrays must be the same size.
seriesColl->Add(u"AW Series 1", categories, System::MakeArray<double>({1, 2}));
seriesColl->Add(u"AW Series 2", categories, System::MakeArray<double>({3, 4}));
seriesColl->Add(u"AW Series 3", categories, System::MakeArray<double>({5, 6}));
seriesColl->Add(u"AW Series 4", categories, System::MakeArray<double>({7, 8}));
seriesColl->Add(u"AW Series 5", categories, System::MakeArray<double>({9, 10}));

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

Le code produit le résultat suivant:

Il existe quatre surcharges différentes pour la méthode d’ajout de séries, qui a été exposée pour couvrir toutes les variantes possibles de sources de données pour tous les types de graphiques:
