2021 Week 27: Can you find the top and bottom performers?

Introduction

Like a fine pinot grigio, I really enjoy a good box-and-whisker plot. There is so much good stat stuff in one place like the min/max, median, top/bottom performers, and outliers in the data set.  I have found, however, that they are rarely used and some business end users find them hard to read. 

 

This week’s challenge isn’t about how to make a box and whisker plot chart easier to read – it’s about how do we incorporate the insightful parts of the box and whisker chart into the Honda Accord of all charts: the bar chart?  Meaning, we do away with arbitrarily created Top N lines in the sand and we use good old fashioned statistics to identify our top/bottom performers.

 

Requirements

  • No sets
  • No LODs except to find the max date (hint)
  • No reference lines for the prior rolling period
  • Parameter action for the # of rolling months.  User must be able to change the number of months included in the rolling months with a single click (no type-in/slider/radio button/drop-down parameters)
  • Sub-Category Color Buckets:
    • Interquartile range
    • At or below 25th percentile 
    • At or above 75th percentile
  • A line should signify the previous rolling N value for sales
  • ’ should be added to the view to easily identify the sub-categories that have experienced sales contraction
  • Same formatting
  • Dashboard size: 1000 X 800
  • Sheets: 2
