At the end of Viz Review, we do our best to designated the last ten minutes to a demo that will show you how to create an effective visualization quickly. Today, I demoed how to created a trellis chart of the percentage of male to female contributors to New York Times crossword puzzles.
Here are the calculations I used for the columns and rows:
Columns: (index()-1)%(round(sqrt(size()))) | Set the table calc to compute using gender.
Rows: int( (index()-1)/(round(sqrt(size())))) | Again, set the table calc to compute using gender.
I made a few mistakes and missteps along the way, but that’s also the beauty of Tableau and a live demo. You can recover quickly and accelerate once you’re back on track.
