最近 7 天的 AVG 未返回结果

AVG of the last 7 days not returning results

我有一个表达式可以提供过去 7 天内 TIMETAKEN 的平均值,但它没有返回任何结果。

=AVG({<STARTDATE={"<$(=date(today()-7))"} >}TIMETAKEN)

我可以用这个得到昨天的 AVG,它有效:

=AVG({<STARTDATE={"$(=Date(Today()-1))"}>} TIMETAKEN)

我使用了以下表达式来实现:

=AVG({<STARTDATE=
{"$(=Date(Today()-7))","$(=Date(Today()-6))","$(=Date(Today()-5))",
"$(=Date(Today()-4))","$(=Date(Today()-3))","$(=Date(Today()-2))",
"$(=Date(Today()-1))"}>}TIMETAKEN)

试试这个

count({<Date={"=Date>(today()-7)"}>}[Date])

的额外学分
count({<Date={"=Date<(today())"}*{"=Date>(today()-7)"}>}[Date])
