I want to count number of text in a column including 3 different text ( "A", "B","C"). However I want to count texts distinctly according to other 3 different dimensions. ( "Part number", "Operation no", "Alternative no").
For example, below table should give me 2 "A", 1 "B" as a result.
And after this, I want to show result in a pie chart regarding numbers of "A", "B", "C".
