Как создать таблицу с низким низким открытием с помощью pandas

Question

У меня есть набор данных, который выглядит ниже, который я могу передать в файл python из файла. Я хотел бы использовать pandas для создания диаграммы HLOC для каждой минуты, начиная с нулевого времени, равным 9:46, используя метод asof .... Я также хотел бы знать, как передавать данные в кадр данных pandas в виде обновлений , Это возможно?
