I'm still getting started with Tableau. I'm sure someone has already asked something similar but I'm still getting acquainted with the terminology.
In the data set, we asked the several questions with the same answer choices (like what is the availibility of vegetables: above normal, normal, below normal; what is the availibilty of cereals: above normal, normal, below norma)
So, I'd like to present in a dashboard one bar graph like below but with a filter that lets the user select the commodity. Could some one give me the brain power, to create a filter that allows users to select from the commodity columns ?
