Установить маркер диаграммы
Aspose.Slides для C++ предоставляет простой API для автоматической установки маркера серии диаграммы. В следующей функции каждый маркер серии диаграммы будет автоматически получать различный символ по умолчанию.
Пример кода ниже демонстрирует, как автоматически установить маркер серии диаграммы.

Установить параметры маркера диаграммы
Маркеры могут быть установлены на точках данных диаграммы внутри конкретной серии. Чтобы установить параметры маркера диаграммы, выполните следующие шаги:
- Создайте экземпляр класса Presentation.
- Создайте диаграмму по умолчанию.
- Установите изображение.
- Возьмите первую серию диаграммы.
- Добавьте новую точку данных.
- Запишите презентацию на диск.
В приведенном ниже примере мы установили параметры маркера диаграммы на уровне точек данных.

Применить цвет к точкам данных
Вы можете применить цвет к точкам данных на диаграмме, используя Aspose.Slides для C++. Классы IChartDataPointLevelsManager и IChartDataPointLevel добавлены для получения доступа к свойствам уровней точек данных. Эта статья демонстрирует, как вы можете получить доступ и применить цвет к точкам данных в диаграмме.
