Last week, I received a question from a developer that caused me to hesitate for a while to craft a solution. The complexity of his data situation caused me to remove myself from his example to be able to find a simple solution. What I show in this article is a solution for him and one that can be used in many situations.The developer that created the question said that he had searched for a solution to this dilemma but could not find one. He reported that some solutions were close to what he needed, but he was unsuccessful in finding his answer.This solution is a general use Tableau technique, so I thought this method would make a useful article. In some ways, the solution is so simple that I hesitated to write this, but I’ve learned that things like this will benefit people in the future if I take the time to show how it is done.
