Working with Charts

Fill and stroke formatting can be set for chart series, data points, and markers. To do this, you need to use the properties of the ChartFormat type in the ChartSeries, ChartDataPoint, and ChartMarker classes, as well as aliases for some properties, such as ForeColor, BackColor, Visible, and Transparency in the Stroke class.

The following code example shows how to set series color:

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");

The following code example shows how to set line color and weight:

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);
