Я использую androidplot для отображения графика, метки повторяются.Я искал форумы, и stackoverflow не нашел никакого решения.
Теперь я заметил, что если размер массива для оси x или оси y меньше 10, значения массива дублируются.
На снимках экрана показана левая ось, повторяющая значение 0,1,2.Значения оси X повторяются.Каково ваше лучшее предложение по решению этой проблемы с повторяющимся ярлыком?Любая помощь будет благодарна.Если вам нужна дополнительная информация, дайте мне знать.
