У меня есть годовые данные, которые состоят из строк без дат. И это выглядит так:
20110101
5.194
0.007
0.000
0.000
0.000
0.845
2.578
12.428
.
.
Он начинается 01.01.2011 и заканчивается 31.12.2011. Я хочу разбить данные на месяцы. Например; первые 31 день для января, следующие 28 дней для февраля ..
