Thanks Ken! This will be useful down the road.
Instead of using that method I have attached the sample superstore dataset with the basic premise of what I am trying to do attached in the workbook.
Customers represent aircraft in this instance and I am counting them distinctly in a dual axis bar graph. The Field 1 represents profit value by category and field 2 represents sales value by field. The values for both fields are the same. I have create a parameter to show the count of costumers within each field value by segment.
What I want to do is instead of having to use the parameter, replace the segment card with the field values (the field values would be the X asis, "Terrible" "Good" "Excellent" etc) and have unique counts of costumers in each. Does this make sense? Workbook attached.
