You didn't post what the "syntax errors" are, so it's hard to evaluate what went wrong. I suspect the problem is a technical one: precisely seven days earlier from the time may or may not lie on the start of a day. If it does not lie on the start of a day, then the daily summaries cannot be used to calculate 'wind' statistics. But, without seeing the "syntax error", I'm just guessing.
Why not just use the search list extension example that comes with WeeWX? It creates a tag $seven_day, which does what you want. See the section *Extending the list <http://www.weewx.com/docs/customizing.htm#extending_the_list>* in the Customization Guide. -tk On Fri, Sep 4, 2020 at 4:00 AM Phil Green <phil.g0...@gmail.com> wrote: > Thanks for the info. > Where would I change the > $week to $span($day_delta=7) > > In the actual report file, in my case hilo.inc or in some definition > elsewhere to set the aggravation period? > I have tried it in hilo.inc > changing:- > #set $archive_data = [('day', $day), ('week', $week), ('month', $month), > ('year', $year), ('rainyear', $rainyear)] > to: > #set $archive_data = [('day', $day), ('week', $span($day_delta=7)), > ('month', $month), ('year', $year), ('rainyear', $rainyear)] > but it causes syntax errors. > So where would I change the definition of $week to a rolling 7 day period? > Regards > Phil > > On Tuesday, September 1, 2020 at 12:36:02 PM UTC+1 graha...@gmail.com > wrote: > >> → see $span($day_delta=7) for rolling 7 days (vs $week for since start of >> week) >> >> On 1 Sep 2020, at 7:27 am, Tom Keffer <tke...@gmail.com> wrote: >> >> NB: The weekly statistics start *Sunday*.
