Examples

Shows how to work with data labels of a bubble chart.

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

SharedPtr<Chart> chart = builder->InsertChart(ChartType::Bubble, 500, 300)->get_Chart();

// Clear the chart's demo data series to start with a clean chart.
chart->get_Series()->Clear();

// Add a custom series with X/Y coordinates and diameter of each of the bubbles.
SharedPtr<ChartSeries> series = chart->get_Series()->Add(u"Aspose Test Series", MakeArray<double>({2.9, 3.5, 1.1, 4.0, 4.0}),
                                                         MakeArray<double>({1.9, 8.5, 2.1, 6.0, 1.5}), MakeArray<double>({9.0, 4.5, 2.5, 8.0, 5.0}));

// Enable data labels, and then modify their appearance.
series->set_HasDataLabels(true);
SharedPtr<ChartDataLabelCollection> dataLabels = series->get_DataLabels();
dataLabels->set_ShowBubbleSize(true);
dataLabels->set_ShowCategoryName(true);
dataLabels->set_ShowSeriesName(true);
dataLabels->set_Separator(u" & ");

Shows how to work with data labels of a pie chart.

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

SharedPtr<Chart> chart = builder->InsertChart(ChartType::Pie, 500, 300)->get_Chart();

// Clear the chart's demo data series to start with a clean chart.
chart->get_Series()->Clear();

// Insert a custom chart series with a category name for each of the sectors, and their frequency table.
SharedPtr<ChartSeries> series =
    chart->get_Series()->Add(u"Aspose Test Series", MakeArray<String>({u"Word", u"PDF", u"Excel"}), MakeArray<double>({2.7, 3.2, 0.8}));

// Enable data labels that will display both percentage and frequency of each sector, and modify their appearance.
series->set_HasDataLabels(true);
SharedPtr<ChartDataLabelCollection> dataLabels = series->get_DataLabels();
dataLabels->set_ShowLeaderLines(true);
dataLabels->set_ShowLegendKey(true);
dataLabels->set_ShowPercentage(true);
dataLabels->set_ShowValue(true);
dataLabels->set_Separator(u"; ");
