Counting multiple values in a single column

Hi there

I am learning BI. Right now, for simplistic reasons, I have a column of postal codes. I would like to count how many postal codes begin with "A," how many begin with "B," how many begin with "C," and so on.

I would like to be able to place this on a map, where the bubble size on the map indicates the number of "A's," the number of "B's," etc.

Any help would be much appreciated 🙂

@LearningBI1986 Perhaps create a DAX measure like this?

Bubble Size Measure =
  VAR __PC = MAX('Table'[PostalCode])
  VAR __FirstChar = LEFT(__PC, 1)
  VAR __Table = FILTER(ALL('Table'), LEFT([PostalCode], 1) = __FirstChar)
  VAR __Result = COUNTROWS(__Table)
RETURN
  __Result

@Greg_Deckler 

Thank you for getting back! That looks promising.
If you don't mind, I'm going to attempt to paste a screenshot here. If you could tell me what I'm doing wrong, I would really appreciate it 🤔Screenshot 2023-05-02 133517.png

 

@LearningBI1986 you put in __Merge2 but __Merge2  variable not you create see agian your code you create __Table Variable.
VAR  __Result = COUNTROWS(__Table) 

THANK YOU!!

@LearningBI1986 Where that red underline is, that needs to be __Table, not __Merge2.
