Как передать значение в линейном графике в flex, из базы данных, где я использую Java для передачи значения

Question

Я использую трендовые линии из графиков.Я использую Java и передаю значения из базы данных Uins Blazeds [??].Я беру коллекцию массивов, чтобы извлечь значения из базы данных и поместить ее в линии тренда.Так в чем же ошибка в коде и каким должен быть правильный код?
