google gantt dragToZoom / параметры обозревателя

/ 05 апреля 2020

У меня есть диаграмма Ганта (запустите код ниже, чтобы увидеть ее), и я хотел бы иметь увеличение и уменьшение масштаба, чтобы пользователи могли видеть соответствующую информацию в Ганте, который распространяется на несколько лет и множество строк. В этом текущем коде пользователь даже не видит все строки Ганта (я не уверен, почему) Гант, по-видимому (я добавил его в код, и он не работает).

Как я могу сделать эту работу / любые указания по реализации этой функции масштабирования будут полезны.
