Используйте amchart в сортируемом div с разной шириной

У меня есть страница, созданная с помощью начальной загрузки, и у меня есть 2 разных раздела на этой странице, первый из которых использует «col-lg-12», а второй использует «col-lg-6», оба из них можно перетаскивать. Я хочу поместить в них несколько диаграмм, все работает нормально, и мои диаграммы реагируют, но когда я переместил div в большую секцию в маленькую секцию, адаптивная функция перестает работать и не изменяет размер автоматически. мой HTML-код
