RANKX not working right?

[Nick_Kalichava]

Hi, experts!

I have a problem with RANKX,

I used 
Rank by Quantity = 
RANKX(
ALL(TABLE),
COUNTA(TABLE[COLUMN])
)

and this solution did not work,
I tinkered with this dax and it only works this way - 
Rank by Quantity = 
RANKX(
ALL(TABLE[COLUMN]),
CALCULATE(COUNTA(TABLE[COLUMN]))
)

Why?

@Nick_Kalichava Because of you remove all rowcontext filter using ALL(Table) .
your table in plot for e.g class and student and you count student and find rank that which class first rank by student count for that you need remove only student filter not class filter because if you remove class filter so it's give all class before same rank . in short ALL in table means you remove that table all filter thats you APPLY IN report and plot in table and matrix etc.

@Nick_Kalichava I hope you geting my point.
