Androidplot - метки X-Axis обрезаны
Я создаю столбчатую диаграмму, но столкнулся с проблемой, связанной с обрезкой меток оси X на планшете. Прилагается правильная раскладка на телефоне и неправильная раскладка на планшете.
Кто-нибудь знает, почему эта проблема возникает на планшете и как ее исправить?

Это мой код для создания гистограммы.
