Assuming you have a field [Profit] and that [X] and [Y] parameters are such that X=10 means 10%, you can do the following:
1) Select Pie Chart on the marks card.
2) Put formula COUNTD([Customer]) on the Angle card.
3) Create a calculated field with the following formula that you drag onto the color card:
if [Profit]>[x]/100 then ">"+STR([x])+"%"
elseif [Profit]<[y]/100 then "<"+STR([y])+"%"
Does that help?
What have you tried so far?
When you say, "Let's take superstore data", are you implying that you want someone to set it all up for you in superstore?
What really should happen here is that you take a good stab at it. Create the two parameters. Create the three calcs. Do it in the version of Tableau that you have installed so that I don't set it up in a higher version and then you say, "I can't read that version. My version is X."
This logic definitely helps
Actually I am working on a real-time project which I can't attach here and that's why I told Superstore data.
Have created 2 parameters and tried with Sets, anyway now it's working with Calculated fields
Anyway Thanks for your reply on my query
