Count of Max date

[garry107]

Hi,

Can't figure out this simple problem:

DATES:
LOAD id, Date#(date) as date, status INLINE [
id, date, Area
A, 01/01/2018, 18

B, 02/02/2018, 25

B, 02/03/2018, 26
C, 03/03/2018, 31
D, 04/04/2018, 42

D,04/05/2018, 43    

D, 04/05/2018, 44];

I'm trying to create an expression to:

- count (Area) where Date = maxDate for eg: for id 'D' there are three dates, trying to get count when date is max which is 04/05/2018. Same for id B where date is maxdate which is 05/03/2018. where date in format of MM/DD/YYYY.

Would appreaciate the help.

Count({$<Date={"=$(=Max(Date))"}>} Area)

May be this

Sum(Aggr(If(Max(TOTAL <id> date) = date, 1, 0), id, date))

Or this

Sum(Aggr(If(Max(TOTAL <id> date) = date, Sum(1), 0), id, date))

Hey,

the above worked. Another question, if I am looking the change in records.

For example:

now with the above, I get this

id,date, Records count

A, 01/01/2018, 18

B,02/03/2018,26

C, 03/03/2018,31

D,04/05/2018,44

i would like to see this

A, 01/01/2018, 18

B,02/03/2018,(26 - 18)

C, 03/03/2018,(31 - 26)

D,04/05/2018,(44 - 31)

How can this be achieved?

This

RangeSum(

Sum(count), -Above(Sum(count))

)

where to insert set identifier '1'?

[sunny_talwar]

not sure what you mean?

[garry107]

for the above expression, I dont need the chart to change with any date selection

Oh okay... may be this

RangeSum(

Sum({1} count), -Above(Sum({1} count))

)
