The Bar of Pie Chart is a built-in chart type in Excel. Pie charts are meant to express a "part to whole" relationship, where all pieces together represent 100%.

Pie charts work best to display data with a small number of categories (2-5). The Bar of Pie Chart provides a way to add additional categories to a pie chart without generating a pie chart too complex to read. When configuring a Bar of Pie chart, Excel provides a setting that moves the smallest n slices of the pie to the bar, where n can be adjusted to suit the data.

Bar of pie charts should be avoided when there are many categories, or when categories do not total 100%. The human eye has trouble comparing the relative size of slices in a pie chart, and this problem is magnified with the pie of pie variety.
