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

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.

dataLabels->set_ShowLeaderLines(true);
dataLabels->set_ShowLegendKey(true);
