Last month I had a great experience in the plank challenge! Despite the fact that I did not achieve the goal (100 minutes in 30 days), I did something more important for myself: I made a habit of doing the plank every day and till today I stick to this rule. This challenge was inspired by Kate Strachnyi and initiated by Laura Strudeman who achieved the goal in this challenge and who did a great Tableau viz . I decided to make my own too: In this dashboard, I applied the new Action 'Change Set Values' that was implemented based on two sets: by the person and by date. It allows comparing the challenge progress speed among competitors over time. This analysis was inspired by materials from Tableau Conference 2018 .
