Мне удалось создать красивый график, но я хочу добавить "цикл", который масштабируется до определенного порога, созданного мной (95-й процентиль). На увеличенном изображении я хотел бы иметь возможность добавлять текст (чтобы показать, какие значения имеет x и y), возможно ли это? Ниже я нарисовал иллюстрацию того, как я хочу, чтобы это выглядело, с кодом внизу (извините за количество точек данных).

решение1
Этот ответ просто показывает некоторые незначительные улучшенияОтвет сурка уже отличный. Я определяю координату для увеличенияпервыйи затем используйте эту координату, чтобы добавить красные пунктирные линии, разместить узел «на шпионе» и написать координаты точки увеличения под увеличением. (Я также решил разместить текст координатниже(Увеличение, потому что тогда ничего не перекрывается.)
Более подробную информацию можно найти в комментариях к коду.
