 If no logs seen, see  [[FAQ#I_can.E2.80.99t_find_my_data_files.21|FAQ: I can't find my data files]]. Also note, this '''Data logs''' viewer is only for viewing monthly log files (not any other files in the same ''data'' directory), the column headings for standard monthly log files will always be shown at the top of the screen.
-==Viewing summary figures for a month or period==
-In the '''View''' menu, select ''This month'', and by default a summary for the current calendar month will be calculated mostly from the daily summary log (therefore not including current meteorological day). To view for a different month (or if you use 9am/10am rollover, if '''current local time on the 1st day of a month''' is before rollover time so the log for the current calendar month has not been started), select the month and year required using the options at bottom left, click ''Update Display'' and the revised summary will be calculated.
-Alternatively you can select ''This period'' and by default, without selecting different dates, ''This period'' shows the equivalent calculation for yesterday. You can select a start date and end date then click ''Update Display'' to get the equivalent calculation for part of a month or any other period.
-Some of the displayed results are for observations not in the daily summary log and are derived from the monthly logs (e.g. average wind speed) or the weather diary (snow).
-Note that many parameters are different to those available as web tags.
-*For example, the day number shown on screen is the meteorological day (changing at rollover and that may be at 9am/10am) as that date appears in dayfile.txt, but when a timestamp (with time and date) is given in a web tag the date is a calendar date (always changing at midnight).
-*As an example of differences in reported statistics, the screen shows total number of dry or wet days in the month, the web tags report longest dry or wet period in the month.
