Я использую API Карт Google для отображения местоположения учетной записи и функции, которая будет отображать соседние местоположения аккаунта. Проблема в том, что я хотел бы увеличить масштаб, чтобы показать маркеры, когда вызывается функция getNearbyAccounts. При текущем уровне масштабирования вы не можете видеть все маркеры. Это просто похоже, что куча маркеров все смешалась.увеличить на карте маркеров google

Спасибо за любую помощь.
Что именно вы пытаетесь сделать? Увеличить, чтобы соответствовать всем маркерам? Масштабировать, чтобы соответствовать определенному подмножеству маркеров? Что вы пробовали? Вы видели метод [fitBounds в документации] (https://developers.google.com/maps/documentation/javascript/reference#Map)? – geocodezip
