Arbeiten mit ChartSeries

Mit Aspose.Words können Benutzer auf verschiedene Arten mit ChartSeriesCollection arbeiten.

Arbeiten mit ChartSeriesCollection des Diagramms

Schauen wir uns die Sammlung ChartSeries an. Alle Diagrammserien sind über ChartSeriesCollection verfügbar:

For complete examples and data files, please go to https://github.com/aspose-words/Aspose.Words-for-C
// Get chart series collection.
System::SharedPtr<ChartSeriesCollection> seriesColl = chart->get_Series();
// Check series count.
std::cout << seriesColl->get_Count() << std::endl;

Arbeiten mit einer einzelnen ChartSeries -Klasse

So arbeiten Sie mit einer bestimmten Serie:

For complete examples and data files, please go to https://github.com/aspose-words/Aspose.Words-for-C
// Get first series.
System::SharedPtr<ChartSeries> series0 = shape->get_Chart()->get_Series()->idx_get(0);

// Get second series.
System::SharedPtr<ChartSeries> series1 = shape->get_Chart()->get_Series()->idx_get(1);

// Change first series name.
series0->set_Name(u"My Name1");

// Change second series name.
series1->set_Name(u"My Name2");

// You can also specify whether the line connecting the points on the chart shall be smoothed using Catmull-Rom splines.
series0->set_Smooth(true);
series1->set_Smooth(true);

Bitte sehen Sie das Ergebnis unten:

Alle einzelnen ChartSeries haben Standardoptionen für ChartDataPoint. Bitte versuchen Sie, sie mit dem folgenden Code zu ändern:

For complete examples and data files, please go to https://github.com/aspose-words/Aspose.Words-for-C
// Specifies whether by default the parent element shall inverts its colors if the value is negative.
series0->set_InvertIfNegative(true);

// Set default marker symbol and size.
series0->get_Marker()->set_Symbol(MarkerSymbol::Circle);
series0->get_Marker()->set_Size(15);

series1->get_Marker()->set_Symbol(MarkerSymbol::Star);
series1->get_Marker()->set_Size(10);

So arbeiten Sie mit einzelnen ChartDataPoint von ChartSeries

Mit ChartDataPoint können Sie die Formatierung eines einzelnen Datenpunkts der Diagrammreihe anpassen:

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

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

// Get first series.
System::SharedPtr<ChartSeries> series0 = shape->get_Chart()->get_Series()->idx_get(0);
// Get second series.
System::SharedPtr<ChartSeries> series1 = shape->get_Chart()->get_Series()->idx_get(1);
System::SharedPtr<ChartDataPointCollection> dataPointCollection = series0->get_DataPoints();

// Set explosion.
dataPointCollection->idx_get(0)->set_Explosion(50);

// Set marker symbol and size.
dataPointCollection->idx_get(0)->get_Marker()->set_Symbol(MarkerSymbol::Circle);
dataPointCollection->idx_get(0)->get_Marker()->set_Size(15);

dataPointCollection->idx_get(1)->get_Marker()->set_Symbol(MarkerSymbol::Diamond);
dataPointCollection->idx_get(1)->get_Marker()->set_Size(20);

// Add data point to the third point of the second series.
series1->get_DataPoints()->idx_get(2)->set_InvertIfNegative(true);
series1->get_DataPoints()->idx_get(2)->get_Marker()->set_Symbol(MarkerSymbol::Star);
series1->get_DataPoints()->idx_get(2)->get_Marker()->set_Size(20);
System::String outputPath = outputDataDir + u"WorkWithSingleChartDataPoint.docx";
doc->Save(outputPath);
