Then i tried to fill the missing daily rainfalls data (using data from other stations near to me) by editing the dayfile.txt for the days from feb 13th to 17th but this worked partially:
feb 13th: 6.2 mm OK on the monthly graph
feb 14th: 1.0 mm OK
feb 15th: 3.7 mm Ok
feb 16th: 27.7 mm no data on graph
feb 17th: 19.2 mm no data on graph
(feb 18th an feb 19th : no rain) I didn't edit any other file, what's wrong ?
Ciao Aldo
