Линейный график графика с использованием org.openxmlformats.schemas.drawingml.x2006.chart

Question

1 Я хочу построить три линии на графике, используя Apache POI с OpenXmlFormats в Excel, однако я могу построить две линии, но не могу построить третью линию, я не знаю почему.пожалуйста, помогите мне построить три линии на одном графике.Я делюсь кодом для построения 2-х строк. [2] Я добавил картинку, которую хочу получить в результате.[3] Как построить несколько диаграмм в одном файле Excel.

Answer 1

Примечания

Поскольку вы не предоставили никаких тестовых данных (например, файл XLS или CSV), я выбрал 3 известных города США с их среднемесячной температурой .

Вы также не предоставили желаемый результат (т. Е. Как должен выглядеть ваш предпочтительный график в конце).Поэтому я выбрал простую линейную диаграмму с одной осью значений и 3 различными сериями (которые принадлежат одной и той же системе ценностей).

Результирующий график выглядит следующим образом (вLibreOffice):
