Count Top 1 Rank per day

[JasonCou]

Hey guys,

I'm trying to get a column that shows the number of days that specific team has ranked 1st

I have a ranking measure based on a score measure that looks like this:

The data has a colum for the Team Name, the points and the date which is filtered using an date slicer.

I'm trying to get a rank for each date within the slicer and count how many times each team has ranked 1st place in each date.

It worked wonderfully, thank you very much. 
I'm having a little trouble understanding how did you archive it! How does the meassure work? (logic wise)

@JasonCou 

this is the sample data i have used: 

result : 

power bi result : 

measure : 

rank measure = 

rnk = 
RANKX(
    ALLSELECTED(tbl_rank[Team]),
    [total points],
    ,DESC
)

nb of days measure

nb of days n1 = 

var ds = 
ADDCOLUMNS(
    CALCULATETABLE(
    SUMMARIZE(
        tbl_rank,
        tbl_rank[date],
        tbl_rank[Team]
    ),
    ALLSELECTED(tbl_rank[Team])
    ),
    "@r" , [rnk]
)


var s = 
GROUPBY(
    ds,
    [@r],
    tbl_rank[Team],
    "c", COUNTX(CURRENTGROUP() , 1 )
)

return 

SUMX(
    
    FILTER(
        s,
        tbl_rank[Team] in VALUES(tbl_rank[Team]) && [@r] = 1 
    ),
        [c])

hope this works for you .
