Удалите недостающее пространство даты и метку-наклейку из подсвечника графика matplotlib

Question

В моей программе я создал свечу по оси и график данных по оси2.Для графика свечи я создал переменную с именем data.это переменная типа словаря Python.где мне назначена дата . 'date': ['2018/10/30', '2018/11/03', '2018/11/04', '2018/11/05', '2018/11/ 07 ',' 2018/11/10 ',' 2018/11/11 ']. другая клавиша - «открыть», «высоко», «низко», «закрыто» и «объем»
Здесь даты «2018/10/30» и «2018/11/03» означают пробел в дате.
Здесь также даты «2018/11/07» и «2018/11/10» существуют.промежуток даты .
Поэтому, когда я создаю свой график подсвечника, берется недостающее пространство даты. Как я могу удалить это недостающее пространство даты.моя программа:

Answer 1

Я решил «Удалить отсутствующее пространство даты и xtricklabel из графа matplotlib». Таким образом, в моем массиве данных я заменил даты целыми числами, начиная с 0. Я также установил xtricklabel со временем.
