All in Tableau Sets
Stacked bar charts are a brilliant visual for displaying how individual segments contribute to the overall value of a category, and how a category ranks in relation to other categories. Like all data visualizations however, it has some weaknesses.
One of the biggest weaknesses of a stacked bar chart is that it's hard to compare bar segments when they don't have a shared baseline. Comparing the first bar segment is straightforward, but comparing the 3rd or 5th segment is cumbersome.
Sets are a powerful Tableau tool that can be used in innumerable ways. One of the most useful (and eye-catching!) ways to use sets, is in combination with Dashboard or Worksheet Actions.
This combination allows us to update the values of our sets simply by interacting with our dashboards and worksheets. We can add values to our sets, assign values, or remove values, just based on our clicks.
Did you know you can reference Tableau Sets in calculations? Most Tableau users don’t.
Referencing a set in a calculation provides you the ability to filter a calculation, rather than an entire worksheet, based on end-user selection.
Why is that valuable?
