Werken met grafieken

Vul-en lijnopmaak kan worden ingesteld voor grafiekreeksen, gegevenspunten en markeringen. Hiervoor moet u de eigenschappen van het ChartFormat - type in de klassen ChartSeries, ChartDataPoint en ChartMarker gebruiken, evenals aliassen voor sommige eigenschappen, zoals ForeColor, BackColor, zichtbaar en transparantie in de klasse Stroke.

Het volgende codevoorbeeld laat zien hoe de kleur van de serie moet worden ingesteld:

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

auto shape = builder->InsertChart(ChartType::Column, 432, 252);

auto chart = shape->get_Chart();
auto seriesColl = chart->get_Series();

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

// Create category names array.
auto categories = System::MakeArray<System::String>({ u"AW Category 1", u"AW Category 2" });

// Adding new series. Value and category arrays must be the same size.
auto series1 = seriesColl->Add(u"AW Series 1", categories, System::MakeArray<double>({ 1, 2 }));
auto series2 = seriesColl->Add(u"AW Series 2", categories, System::MakeArray<double>({ 3, 4 }));
auto series3 = seriesColl->Add(u"AW Series 3", categories, System::MakeArray<double>({ 5, 6 }));

// Set series color.
series1->get_Format()->get_Fill()->set_ForeColor(Color::get_Red());
series2->get_Format()->get_Fill()->set_ForeColor(Color::get_Yellow());
series3->get_Format()->get_Fill()->set_ForeColor(Color::get_Blue());

doc->Save(u"ColumnColor.docx");

Het volgende codevoorbeeld laat zien hoe u lijnkleur en gewicht instelt:

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

auto shape = builder->InsertChart(ChartType::Column, 432, 252);

auto chart = shape->get_Chart();
auto seriesColl = chart->get_Series();

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

// Adding new series.
auto series1 = seriesColl->Add(u"AW Series 1", System::MakeArray<double>({ 0.7, 1.8, 2.6 }), System::MakeArray<double>({ 2.7, 3.2, 0.8 }));
auto series2 = seriesColl->Add(u"AW Series 2", System::MakeArray<double>({ 0.5, 1.5, 2.5 }), System::MakeArray<double>({ 3, 1, 2 }));

// Set series color.
series1->get_Format()->get_Stroke()->set_ForeColor(Color::get_Red());
series1->get_Format()->get_Stroke()->set_Weight(5);
series2->get_Format()->get_Stroke()->set_ForeColor(Color::get_LightGreen());
series2->get_Format()->get_Stroke()->set_Weight(5);

doc->Save("LineColorAndWeight.docx");
