I have a dataset with the value of various items on different dates. I first need to calculate ratio by dividing the value of an item on a particular date with the earliest value in the chosen date filters. I then need to show the per day ratio of all items (columns I & J) as the desired output.
I am able to get the "first value" in the filtered table by using the following formula:
first_cr =
VAR item = MAX('Table 1'[item])
VAR min_updated = CALCULATE(
MIN('Table 1'[last_updated]),
'Table 1'[item] = item,
ALLSELECTED('Table 1')
)
RETURN
CALCULATE(
AVERAGE('Table 1'[cr]),
'Table 1'[last_updated] = min_updated,
'Table 1'[item] = item,
ALLSELECTED('Table 1'[fk])
)
However, I am unable to figure out how to calculate the average of all the individual item ratios at just the date level. I guess I need to use AVERAGEX somehow, but not sure how. Perhaps my first_cr formula could use more refinement.
I'd appreciate any help or guidance in the right direction. Thanks for your time.
Solved! Go to Solution.
I was able to write a working formula for my requirement. If anyone can refine it better, I'd appreciate that...
ret =
var lastUpdated = MAX(Sheet1[Date])
var tbl = ALLSELECTED(Sheet1)
RETURN
CALCULATE(
AVERAGEX(
Sheet1,
var i = Sheet1[Item]
var minUpdated = CALCULATE(
MIN(Sheet1[Date]),
Sheet1[Item] = i,
tbl
)
var first_cr = CALCULATE(
AVERAGE(Sheet1[Return]),
Sheet1[Date] = minUpdated,
Sheet1[Item] = i,
tbl
)
RETURN Sheet1[Return] / first_cr
),
Sheet1[Date] = lastUpdated,
tbl
)

Hi @dpc_development ,
Glad to hear that. Please accept your reply above as a solution so that people who may have the same question can get the solution directly.
