Dayfile.txt

Cumulus maintains a daily file of the highs and lows of each day, as well as a few other nuggets of information. The data contained in the file are used to build the graphs.

The file is called dayfile.txt which can be viewed in a text editor or imported into various database systems or spreadsheets to manipulate as you wish.

Tip -- take a copy of the file to work on it elsewhere.

Important: The date format uses two digits for the year. Do not edit this file using Excel or any similar tool that recognizes dates, as it is likely to change the dates to have four figure years, and then Cumulus will no longer be able to use the file. Also, make sure that editing does not create any blank lines in file, all must start with date and include some of the parameters listed in sequence.
