Distinctcount linked to another column

[phaum1967]

Hi PowerBI community

I have a table like this:  

column nme :  Speciality, Date of operation,...

I want to have a distinctcount on date in order to count all different dates for each speciality.

Of course If I do a distinctcount(date) it does not work as it will count all dates but without taking account my need of have number of date by specilaity.

I tried calculcate(distinctount(date); speciality) but it does nothing.

Any help is welcome...

Hi,

You should drag speciality to the X axis of the Graph and then drag the Distinctcount measure to the value section.  Anyways, if you want to write a formula, write this measure:

=CALCULATE(DISTINCTCOUNT(Data[Date of operation]),Data[Speciality]="XXX")

Replace XXX with the specific speciality.

Hi @phaum1967

“have a distinctcount on date in order to count all different dates for each speciality”

To achieve requirement above, create a column

Column = CALCULATE(DISTINCTCOUNT(Sheet1[Date of operation]),ALLEXCEPT(Sheet1,Sheet1[Speciality]))

Hi,

Write the normal distinctcount function and in the filter/slicer, select any speciality.

Thanks but I want to present datas in a graph that show monthly activities per speciality. So slicer does not help.

An other idea?

thanks
