问题
As you can see from my picture, I have a list of bowling scores and some running averages. The issue I cannot seem to solve is I would like to be able to see the change in average between a game and the previous game. If the average goes down, it would say -1.2% for example or +2.1% if it goes up. I would really like negative averages to be in red and positive ones in green if that is possible.
Here is a copy of my sheet with the desired output in column G.
回答1:
first you will need running average:
=ARRAYFORMULA(QUERY(TRANSPOSE(QUERY(TRANSPOSE(IF(ISNUMBER(
ARRAY_CONSTRAIN(SPLIT(SORT(REPT("♦ ", ROW(INDIRECT("A1:A"&COUNTA(A2:A)))-1), 1, 0)&
"♦"&TEXTJOIN("♦", 1, C2:C), "♦"), 999^99, COUNTA(A2:A))),
ARRAY_CONSTRAIN(SPLIT(SORT(REPT("♦ ", ROW(INDIRECT("A1:A"&COUNTA(A2:A)))-1), 1, 0)&
"♦"&TEXTJOIN("♦", 1, C2:C), "♦"), 999^99, COUNTA(A2:A)), )),
"select "&TEXTJOIN(",", 1, IF(LEN(A2:A),
"avg(Col"&ROW(A2:A)-ROW(A2)+1&")", ))&"")),
"select Col2", 0))
then you can do:
=ARRAYFORMULA(IF(A2:A<>"", {0; (INDIRECT("F2:F"&ROWS(F3:F))-F3:F)*-1}, ))
and finally color format it:
回答2:
You get the change percentage using: =ROUND((C3-C2)/C2*100,2) in G3:G20.
Check:
- For going down from 145 to 123 this returns (with no rounding) -15.17241379.
- 145 + (145 * -15.17241379 / 100) = 123
For the colouring:
- Select the cells G3:G20.
- Go to -> Format -> Conditional formatting -> Format rules -> Format cells if… -> Greater than -> 0 -> Formatting style
- -> [Down arrow next to letter A] -> [Pick your colour]
- -> [Down arrow next to (bucket with) fill colour] -> [None]
PS: For the running average you can use: =AVERAGE(C$2:C2) in F2:F20.
Please comment, if and as this requires adjustment / further detail.
