Group by value mappings

Hi all

I have a EL query which I group by responseType.
I have the following value mappings

0 OK
19 NOK-OK
05 NOK-OK
57 NOK-OK
55 NOK-OK
14 NOK-OK
03 NOK-OK
12 NOK-NOK
96 NOK-NOK
87 OK

The value to the left is the responseType
I want to display a table that groups by value mappings i.e.

OK 100
NOK-OK 2
NOK-NOK 3
