#TableauTipTuesday: How to Create a Dynamic Reference Band with Set Actions

Last week when I was teaching DS19, we were coming up with use cases for set actions. We came up with the idea of allowing a user to create their own reference band by lassoing the dates they are interested in. The reference band, via a set action, will then automagically move to the range of dates selected.

Enjoy!

#MakeoverMonday: Messi vs. Ronaldo - Who Took the Fewest Minutes to Score?

I haven't written a blog about Makeover Monday since the end of last year and I want to get back into the habit of blogging, so I'll give a quick review of what could be improved with this week's viz.


What could be improved?

• Curvy lines don't help you see the exact points of the data. When curved lines are drawn, they render to smooth out the lines, therefore misleading the location of the data along the axis. 
• Does the data represent each season or matches within a season? Given that I haven't looked at the data yet, the curved lines make me think the latter.
• Is there a missing title?
• What does the y-axis represent?
• It looks like the data might be goals per match, but that would be misleading since they might have substitute appearances? Would goals per minute normalize the data better?

#TableauTipTuesday: How to Use Set Actions to Maintain the Rank of a Dimension Upon Filtering

One of the drawback of filtering a dimension is that you will lose the rank of a dimension relative to others. This happens because of Tableau's order of operations which dictate that a dimension filter takes effect before a table calculation (rank in this case).

This video shows you how to use Set Actions to filter a dimension while also maintaining the rank.
