Mr. Nielsen, a simple bar chart is so much better!
Another fantastic article from Nielsen, tainted by a pie chart. Want to Increase Store Traffic, Loyalty and Growth? Re-Think the Center Store
The purpose of Nielsen’s pie charts is to compare the % of total trips to the % of total sales. But there’s no way to do it effectively or quickly if your eyes are having to constantly scan back and forth in an attempt to compare their sizes.
Any of the bar/column charts below is a considerable improvement over the pie charts. My favorite of the options below is the bar-in-bar chart. You can quickly see that fill-in/errand trips are the most frequent, but food trips dominate sales. Which is your favorite?
