I have a dataset looking like that mentions below
I want to transform the minute's data to hourly data by adding the values having the same hour on their time index. In one word, I need to group them according to an hour. I have tried several aggregate functions but can't find the desired value. Some of them are giving only integer values and some of them are giving wrong. How can I get the aggregate value according to an hour from here?
Thanks in advance.
