I'd like to calculate mean, lowest and highest temperature every
Delimiters of the intervals on which everything is calculated
Is there something not clear? Try this :

Lowest temperature : -2.9°C at 6:00 of 5/1/1990
Highest temperature : 30.1°C at 17:00 of 26/6/1990
Date, hour and temperature of the selection: N/A, 0:00 of 1/1/1990

Start to display the values from :
