◆ get_Bubble3D()

virtual bool Aspose::Words::Drawing::Charts::IChartDataPoint::get_Bubble3D ( )
pure virtual

Specifies whether the bubbles in Bubble chart should have a 3-D effect applied to them.

Examples

Shows how to use 3D effects with bubble charts.

auto doc = MakeObject<Document>();
auto builder = MakeObject<DocumentBuilder>(doc);
SharedPtr<Shape> shape = builder->InsertChart(ChartType::Bubble3D, 500, 350);
SharedPtr<Chart> chart = shape->get_Chart();
ASSERT_EQ(1, chart->get_Series()->get_Count());
ASSERT_EQ(u"Y-Values", chart->get_Series()->idx_get(0)->get_Name());
ASSERT_TRUE(chart->get_Series()->idx_get(0)->get_Bubble3D());
// Apply a data label to each bubble that displays its diameter.
for (int i = 0; i < 3; i++)
{
chart->get_Series()->idx_get(0)->set_HasDataLabels(true);
chart->get_Series()->idx_get(0)->get_DataLabels()->idx_get(i)->set_ShowBubbleSize(true);
}
doc->Save(ArtifactsDir + u"Charts.Bubble3D.docx");

Implemented in Aspose::Words::Drawing::Charts::ChartDataPoint, and Aspose::Words::Drawing::Charts::ChartSeries.

◆ get_Explosion()

virtual int32_t Aspose::Words::Drawing::Charts::IChartDataPoint::get_Explosion ( )
pure virtual

Specifies the amount the data point shall be moved from the center of the pie. Can be negative, negative means that property is not set and no explosion should be applied. Applies only to Pie charts.

Examples

Shows how to move the slices of a pie chart away from the center.

auto doc = MakeObject<Document>();
auto builder = MakeObject<DocumentBuilder>(doc);
SharedPtr<Shape> shape = builder->InsertChart(ChartType::Pie, 500, 350);
SharedPtr<Chart> chart = shape->get_Chart();
ASSERT_EQ(1, chart->get_Series()->get_Count());
ASSERT_EQ(u"Sales", chart->get_Series()->idx_get(0)->get_Name());
// "Slices" of a pie chart may be moved away from the center by a distance via the respective data point's Explosion attribute.
// Add a data point to the first portion of the pie chart and move it away from the center by 10 points.
// Aspose.Words create data points automatically if them does not exist.
SharedPtr<ChartDataPoint> dataPoint = chart->get_Series()->idx_get(0)->get_DataPoints()->idx_get(0);
dataPoint->set_Explosion(10);
// Displace the second portion by a greater distance.
dataPoint = chart->get_Series()->idx_get(0)->get_DataPoints()->idx_get(1);
dataPoint->set_Explosion(40);
doc->Save(ArtifactsDir + u"Charts.PieChartExplosion.docx");

◆ get_InvertIfNegative()

virtual bool Aspose::Words::Drawing::Charts::IChartDataPoint::get_InvertIfNegative ( )
