Microsoft Excel contains a variety of charts and graphs for data visualization. One of these graphs is the pie chart, which can show a lot of information in a small amount of space. In this blog, we are going to discuss pie charts and their features.

What is a Pie Chart?

A pie chart is a useful tool for displaying different values as a proportion of a whole. It is a circle which is divided into slices that represent a percentage of the total. You can add numbers as percentages or their actual values. There are three types of pie charts: 2-D, 3-D, and doughnut charts.

When to Use a Pie Chart?

Using a pie chart has many advantages, such as:

It can show a lot of information in one look; it allows the viewer to analyze the data at a glance; it doesn’t need much additional explanation, etc.

Like any other kind of graph, the pie chart has its disadvantages as well:

For a large number of data points, the pie chart gets complicated and hard to read. In this case, a bar chart could be better; since pie charts cannot show trends within the data.

Pie of Pie and Bar of Pie

When you have several data points, The data points with lower percentages may not be quite clear, making it difficult to analyze the data. In this case, we can use a ‘pie of pie’ chart which emphasizes the smaller slices in a secondary chart.

How to make Pie of Pie

Suppose we have the following dataset, and we want to make a pie of pie chart.

Example for a pie of pie chart

It’s important to note that, by default, Excel picks the last three points to separate from the main pie chart. So if they are not the lowest percentages, we have to sort the data first. After that, follow the procedure to create the pie chart, except in the last step, instead of the “pie” option, choose “pie of pie.”

As mentioned above, Excel takes the last three data points to separate from the main chart. You can set how you want to separate them.

To do so, double click on the pie chart to open the “Format Data Point” pane. Under the “Series Option” tab, click on the “Split Series By” box to open a drop-down menu.

Here, you can choose the criteria to split the slices. You will have the following options:

  • Position” is the default option. You can change the number of slices to split in the “Values in second pie” box.
  • By choosing “Value,” you can separate the slices with a value less than a specified one.
