get_SecondaryCategories()

IChartData::get_SecondaryCategories() method

Gets the secondary categories if IChartData::get_UseSecondaryCategories is true. Read-only IChartCategoryCollection.

virtual System::SharedPtr<IChartCategoryCollection> Aspose::Slides::Charts::IChartData::get_SecondaryCategories()=0

Remarks

If IChartData::set_UseSecondaryCategories is set to false then IChartData::get_SecondaryCategories returns null and data in IChartData::get_Categories is used both for primary and secondary series. If IChartData::set_UseSecondaryCategories is set to true then data in IChartData::get_SecondaryCategories is used for secondary series and data in IChartData::get_Categories is used for primary series.

Example. What categories are related to series - ChartData.Categories or ChartData.SecondaryCategories?

if (series->get_PlotOnSecondAxis() && series->get_Chart()->get_ChartData()->get_UseSecondaryCategories())
{
    // related categories are series->get_Chart()->get_ChartData()->get_SecondaryCategories()
}
else
{
    // related categories are series->get_Chart()->get_ChartData()->get_Categories()
}
