Donut Chart

Version 15

 

Intro

A donut chart is a circle divided into sections, each of which represents a percentage of the overall chart. This chart type is almost identical to a pie chart; the only difference is that there is a hole in the center, so the sections appear as arcs rather than wedges.

Donut charts contain a single subtype: the nautilus donut chart. For more information about this and other pie-type charts, see Available pie-Type charts.

Powering donut charts

A donut chart requires two columns or rows of data from your DataSet—a category column or row containing the names of each section, and a value column or row containing the corresponding values for each section. The numbers in the values column or row do not need to add up to 100%. For information about value, category, and series data, see Understanding Chart Data.

The sections in a donut chart are arranged from highest to lowest value starting at the top and moving clockwise.

In the Analyzer, you choose the columns containing the data for your donut chart. For more information about choosing data columns, see Applying DataSet Columns to Your Chart.

For more information about formatting charts in the Analyzer, see KPI Card Building Part 2: The Analyzer.

The following graphic shows you how the data from the category and value columns in a typical column-based spreadsheet is converted into a donut chart:

Customizing donut charts

You can customize the appearance of a donut chart by editing its Chart Properties. For information about all chart properties, see Chart Properties. Unique properties of donut charts include the following.

Property

Description

Example

General > Maximum Slices Before 'Other'

Determines the number of slices in the chart that are represented as unique slices—all remaining slices in the chart are aggregated into an "Other" slice. In the example at right, the user entered "6" as the Maximum Slices Before Other value; therefore, the first five slices appear as unique slices, and the remaining slices are grouped into an "Other" slice.

General > Value Format

Determines whether currency symbols are appended to values.

General > Value Decimal Places

Determines the number of decimal places in values.

General > Percent Value Decimal Places

Determines the number of decimal places in values.

General > Unsorted Data Determines whether or not the slices in a pie-type chart are arranged automatically from highest to lowest value. By default, you cannot change the sort order by selecting different options in the Sorting menu. However, if you check the Unsorted Data box, you can use the Sorting menu to change the sort order. For more information, see Sorting the Data in Your Chart.
Legend > Hide Legend When this option is selected, no legend appears next to your pie or donut chart. The example shows a pie chart in which the legend has been hidden.
Legend > Display in Legend Determines whether values from your DataSet display as literal values or as their corresponding percentages in your pie chart. For example, a value from your DataSet might be "26" but take up 35.9% of the pie. Therefore, if you selected Value Only for this property, the legend item would read "26," and if you selected Percentage, the legend item would read "35.9%." If you selected No Label, only the name of each slice would appear in the legend.   

Hover Legend > Hide Legend

When this option is selected, the "hover legend," which normally appears when you mouse over a slice in your pie or donut chart, is hidden from view. 

Hover Legend > Title Text

Lets you customize the summary text that appears above your pie or donut chart's hover legend area (which normally reads "Total").

The example shows a pie chart in which this text has been customized to read "Sum of Amount."

Hover Legend > Title Value

Lets you specify an aggregation type for the summary value in your pie or donut chart's hover legend. By default all of the data in your chart is totaled, but you can change this to show the average, minimum, or maximum amount in the chart.

Hover Legend > Hide Percent Value

When this option is selected, the percent of total value that appears when you mouse over a slice in your pie or donut chart does not appear.
