I am still a bit confused on the need of the switch condition and the requirement. Can you share a sample data and visual you are looking at in the Arena?
Sharing below what I understood. Switch case will be compiled case by case, so based on your formula, none of the CL_RN is counted under B since the previous case is satisfied all gets encoded as A.
Is this what you want to compute?
If yes, how you want to represent all three categories together in a visual, since this recounts the customers and the numbers won’t match with total.
However if your computation is like :
You can modify the switch case to yield this.
