what is the best practice to create graphs for Likert surveys?
I've been having a hard time creating some useful graphs out of Likert surveys. What I want to do is to create something like this in this picture. This is one was created in Tableau using Gantt chart, but I couldn't find what value put on the start and end date because it seems it only takes dates as a value. I hope you understand my poor English, thanks a lot!
