You can edit charts in a variety of ways. For this sample pie chart, we will:

- Add a title.
- Remove the small category of "missing" data.
- Display percentages for the two remaining categories in the chart.

The first thing we'll do is add a title:

Double-click the pie chart to open it in the Chart Editor.

From the Chart Editor menus choose:

Chart
Title

For Title 1, enter Home Internet Service and then click OK.

A descriptive title is now displayed above the pie chart.

Now we'll remove the small category of missing data. For information on missing data, see Handling Missing Data.

From the Chart Editor menus choose:

Series
Displayed

Move Missing from the Display list to the the Omit list and click OK.

The category of missing data has beeen removed from the pie chart, leaving only two categories.

The pie chart clearly shows that most respondents do not have internet service at home, and it looks like almost three-quarters of the respondents are in the No category -- but it might be useful to see the exact percentages.

Double-click one of the two category labels (No or Yes).

Select (check) Percents.

While we're here, let's move the category labels from the outside to the inside of the pie.

Click Format.

Select Inside from the drop-down list.

Deselect (uncheck) Inside labels to suppress the display frame.

Click Continue and then Click OK.

Now percentages are displayed along with the category labels -- and both are displayed inside the pie slices.

The percentages are based on the two categories displayed (73.4 + 26.6 = 100). If you put the category containing missing values back into the pie, the percentages would change.
