Я использую диаграмму / график Google в веб-обозрении для своего кода iOS / Objective c. Но данные, которые у меня есть, слишком длинные, поэтому они прокручиваются относительно всех значений. Но ось Y слишком прокручивается с данными, поэтому трудно определить значения в более поздней части. Можно ли как-нибудь сделать ось Y статичной, которая не будет прокручиваться так долго, как значения на оси x. После одного предложения я попробовал использовать фильтр диапазона, но HTML работает в веб-браузере, но я не могу нажать на диапазон фильтра на устройстве iPhone.
Ниже приведен пример HTML
