Creating Pie of Pie and Bar of Pie charts

Excel 2016 2013 2010 2007 2003
Excel pie charts are useful to display fractions of a whole by splitting a circle into sections. Each section looks like a slice of a pie and represents a category. Such a layout makes it easy to observe relationships between parts, but the smaller becomes the slice (less than 10%) – the harder becomes to estimate it visually.

For example, if you have several companies that operate on the market, you can represent a part of every company on the market as a slice.

This data contains five slices that fall below 10%.

To make smaller slices more visible in a pie chart, Microsoft Excel provides the Pie of Pie and Bar of Pie chart sub-types. Each of these chart sub-types separates the smaller slices from the main pie chart and displays them in a supplementary pie or stacked bar chart. To create a Pie of Pie or Bar of Pie chart, follow these steps:

   1.    Select the data range (in this example, B3:C12).

   2.    On the Insert tab, in the Charts group, click the Insert Pie or Doughnut Chart button:

There are several ways to choose which categories (slices) to display in the secondary pie or bar chart:

Split series by dropdown list in Excel 365
  • Split series by Position (enter the number of positions moved to the secondary chart)
  • Split series by Value (the values less than the specified moved to the secondary chart)
  • Split series by Percentage Value (the values less than the specified percentage moved to the secondary chart)
  • Split series by Custom (drag and drop categories between to charts)

You can then make any other adjustments to get the look you desire:

  • Pie Explosion detaches the slice from the primary chart and moves it closer to the secondary chart
  • Gap Width controls the distance between charts
  • Second Plot Size specifies the relative size of the second chart.
