Pie Chart Percentage Ratio

[#1]

Brand New to QV.

I need to create a Pie Chart that displays the ratio of values in a status field.

The values contained in the status field are W, L, P, B.

I am not sure of the steps:

1. Create a dimension using the status field
2. Do I need to create an expression for each of the values with a default of other for anything that I have not defined?

Any guidance would be helpful. Thank you

Dimension: Status Field

Expression : Count(Status Field)

Number format : Percentage.
