How create class inside a column

[GuillaumePower]

Hello, i would like create class inside a column, to sum some product  by  this class, for example create a class all the 10 items from my column and give it a number or  letter.

Thanks in advance

class with letter for each group  of 3 numbers

1	A
2	A
3	A
4	B
5	B
6	B
7	C
8	C
9	C
10	D
11	D
12	D
13	E
14	E
15	E
16	F
17	F
18	F
19	G
20	G
21	G

In fact,  I  want to divide in some groups a table without using an expression like a switch (A :if >10;B if > 20 and so on).

Simply create 3 class in a table with the same number of elements in each class.

I think that the function SAMPLEAXISWITHLOCALMINMAX could help me, but I have not found the right way to use it. Is it more clear ?

Interesting. That function is not listed in the official documentation

but when you spell it out it will appear

The inofficial documentation is equally vague SAMPLEAXISWITHLOCALMINMAX – DAX Guide
