Just wanted to drop a useful link for you on how to create Donut Charts (With Text) in Tableau.
The suggestions the Kumar gave should get you to the intended result, but if you still have trouble, let us know.
Thank you for your response.
I am sorry to tell you, although your solution can not work, it did give me some useful hints about how to solve my problem.
In fact, after I finish making a ring, I directly drag all the measure values into "Angle" and "Size" and remove all the things I do not want.
Then I make it.
Thank you again for your help.
