Praca z wykresami

Formatowanie wypełnienia i obrysu można ustawić dla serii Wykresów, punktów danych i znaczników. Aby to zrobić, musisz użyć właściwości typu ChartFormat w klasach ChartSeries, ChartDataPoint i ChartMarker, a także aliasów dla niektórych właściwości, takich jak ForeColor, BackColor, widoczny i przezroczystość w klasie Stroke.

Poniższy przykład kodu pokazuje, jak ustawić kolor serii:

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");

Poniższy przykład kodu pokazuje, jak ustawić kolor i wagę linii:

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");
