Hi, I am new to tableau and working on a project:
I have created a dumbell chart viz where the total population is displayed between 2 years 2014 and 2017 for about 70 zip codes.
I want to add a filter such that only the top 10 zip codes are shown which have the greatest decrease in population 2014-2017.
Will a calculated field be required for this? Or is there a simple way to just filter?
For example, I have filtered by Top 10 - variance but it is showing me incorrect figures
