Box and Whisker plots - Changing whiskers
For my next #BestNewTableauSkill I focus on how to extend the whiskers of a box and whisker plot to incorporate the full range of data.
Â
When creating a box and whisker plot in Tableau the default setting is for the whiskers to incorporate data points within 1.5 x the Inter Quartile Range. Whilst this is of course a valid way of representing a box and whisker plot there is an alternative, and some may some, more traditional way of displaying the whiskers; incorporating the full range of data points.
Example default box and whisker plot : Whiskers incorporating 1.5 x the Inter Quartile Range

Example amended box and whisker plot : Whiskers incorporating the full range of data

Changing the Tableau default setting for a box and whisker plot is easy! Right click on the box and whisker plot and select the 'Edit' option; when the pop up box appears change the 'Plot Option' of 'Whiskers extend to' to be 'Maximum extent of the data'.
Â
Your box and whisker plot will now appear as per the second example above; i.e. incorporating the full range of data points.
