]ShapeCollection::AddChart(Charts::ChartType, float, float, float, float) method
Creates a new chart, initializes it with sample series data and settings, and adds it to the end of the shape collection.
System::SharedPtr<Charts::IChart> Aspose::Slides::ShapeCollection::AddChart(Charts::ChartType type, float x, float y, float width, float height) override
Arguments
| Parameter | Type | Description |
|---|---|---|
| type | Charts::ChartType | The type of chart to add. |
| x | float | The x-coordinate of the new chart, in points. |
| y | float | The y-coordinate of the new chart, in points. |
| width | float | The width of the chart, in points. |
| height | float | The height of the chart, in points. |
Return Value
The newly created IChart.
Remarks
The following example shows how to create Chart in PowerPoint Presentation.
// Instantiates the Presentation class that represents a PPTX file
auto pres = System::MakeObject<Presentation>();
// Accesses the first slide
auto slide = pres->get_Slides()->idx_get(0);
// Adds a chart with its default data
System::SharedPtr<IChart> chart = slide->get_Shapes()->AddChart(ChartType::ClusteredColumn, 0.0f, 0.0f, 500.0f, 500.0f);
// Sets the chart title
auto chartTitle = chart->get_ChartTitle();
chartTitle->AddTextFrameForOverriding(u"Sample Title");
chartTitle->get_TextFrameForOverriding()->get_TextFrameFormat()->set_CenterText(NullableBool::True);
chartTitle->set_Height(20.0f);
chart->set_HasTitle(true);
auto chartData = chart->get_ChartData();
auto categories = chartData->get_Categories();
auto chartSeries = chartData->get_Series();
// Sets the first series to show values
chartSeries->idx_get(0)->get_Labels()->get_DefaultDataLabelFormat()->set_ShowValue(true);
// Sets the index for the chart data sheet
int32_t defaultWorksheetIndex = 0;
// Gets the chart data worksheet
System::SharedPtr<IChartDataWorkbook> fact = chartData->get_ChartDataWorkbook();
// Deletes the default generated series and categories
chartSeries->Clear();
categories->Clear();
int32_t s = chartSeries->get_Count();
s = categories->get_Count();
// Adds new series
chartSeries->Add(fact->GetCell(defaultWorksheetIndex, 0, 1, System::ExplicitCast<System::Object>(u"Series 1")), chart->get_Type());
chartSeries->Add(fact->GetCell(defaultWorksheetIndex, 0, 2, System::ExplicitCast<System::Object>(u"Series 2")), chart->get_Type());
// Adds new categories
categories->Add(fact->GetCell(defaultWorksheetIndex, 1, 0, System::ExplicitCast<System::Object>(u"Caetegoty 1")));
categories->Add(fact->GetCell(defaultWorksheetIndex, 2, 0, System::ExplicitCast<System::Object>(u"Caetegoty 2")));
categories->Add(fact->GetCell(defaultWorksheetIndex, 3, 0, System::ExplicitCast<System::Object>(u"Caetegoty 3")));
// Takes the first chart series
System::SharedPtr<IChartSeries> series = chart->get_ChartData()->get_Series()->idx_get(0);
auto dataPoints = series->get_DataPoints();
// Populates series data
dataPoints->AddDataPointForBarSeries(fact->GetCell(defaultWorksheetIndex, 1, 1, System::ExplicitCast<System::Object>(20)));
dataPoints->AddDataPointForBarSeries(fact->GetCell(defaultWorksheetIndex, 2, 1, System::ExplicitCast<System::Object>(50)));
dataPoints->AddDataPointForBarSeries(fact->GetCell(defaultWorksheetIndex, 3, 1, System::ExplicitCast<System::Object>(30)));
// Sets the fill color for the series
series->get_Format()->get_Fill()->set_FillType(FillType::Solid);
series->get_Format()->get_Fill()->get_SolidFillColor()->set_Color(System::Drawing::Color::get_Red());
// Takes the second chart series
series = chart->get_ChartData()->get_Series()->idx_get(1);
// Populates series data
dataPoints->AddDataPointForBarSeries(fact->GetCell(defaultWorksheetIndex, 1, 2, System::ExplicitCast<System::Object>(30)));
dataPoints->AddDataPointForBarSeries(fact->GetCell(defaultWorksheetIndex, 2, 2, System::ExplicitCast<System::Object>(10)));
dataPoints->AddDataPointForBarSeries(fact->GetCell(defaultWorksheetIndex, 3, 2, System::ExplicitCast<System::Object>(60)));
// Sets the fill color for series
series->get_Format()->get_Fill()->set_FillType(FillType::Solid);
series->get_Format()->get_Fill()->get_SolidFillColor()->set_Color(System::Drawing::Color::get_Green());
// Sets the first label to show Category name
System::SharedPtr<IDataLabel> lbl = dataPoints->idx_get(0)->get_Label();
lbl->get_DataLabelFormat()->set_ShowCategoryName(true);
lbl = dataPoints->idx_get(1)->get_Label();
lbl->get_DataLabelFormat()->set_ShowSeriesName(true);
// Sets the series to show the value for the third label
lbl = dataPoints->idx_get(2)->get_Label();
lbl->get_DataLabelFormat()->set_ShowValue(true);
lbl->get_DataLabelFormat()->set_ShowSeriesName(true);
lbl->get_DataLabelFormat()->set_Separator(u"/");
// Saves the PPTX file to disk
pres->Save(u"AsposeChart_out.pptx", SaveFormat::Pptx);
ShapeCollection::AddChart(Charts::ChartType, float, float, float, float, bool) method
Creates a new chart, initializes it with sample series data and settings, and adds it to the end of the shape collection.
System::SharedPtr<Charts::IChart> Aspose::Slides::ShapeCollection::AddChart(Charts::ChartType type, float x, float y, float width, float height, bool initWithSample) override
Arguments
| Parameter | Type | Description |
|---|---|---|
| type | Charts::ChartType | The type of chart to add. |
| x | float | The x-coordinate of the new chart, in points. |
| y | float | The y-coordinate of the new chart, in points. |
| width | float | The width of the chart, in points. |
| height | float | The height of the chart, in points. |
| initWithSample | bool | True to initialize the new chart with sample series data and settings; false to create the chart with no series and only minimal settings, which makes creation faster. |
Return Value
The newly created IChart.
