A Doughnut chart is a circular visual used to show how different categories contribute to a whole. Each segment of the chart represents a category and its proportion of the total.
A Doughnut chart is similar to a Pie chart but contains a blank space in the center. This center space can also provide room for a label or icon. Doughnut charts are most effective when displaying a small number of categories and comparing their contribution to the total.

How to Proceed?
Step 1
Launch Power BI Desktop, create a new report page, and import the required data.
Step 2 Add a Doughnut Chart
From the Visualizations pane, select the Doughnut chart visual.
Step 3 Add Fields to the Doughnut Chart
Add the required fields to the appropriate field wells in the Build visual pane:
Legend – Sport
Values – No of Participants
The Legend field separates the Doughnut chart into different sport categories.
The Values field determines the size of each segment based on the number of participants.
In this example, the Doughnut chart displays the distribution of athletes by sport.
Step 4 Apply Filters
Filters allow you to focus on specific data displayed in the Doughnut chart.
In this example, a Top N filter is applied to the Sport field to display the top five sports based on the number of participants.
This makes the chart easier to read and helps compare the contribution of the top sport categories.
Step 5 Customize the Doughnut Chart
Select the Doughnut chart and use the available options in the Format visual pane to customize the visual.
In this example, I selected a blue background color and set the transparency to 87% to reduce the intensity of the background color.
I also added a suitable title and customized the font size, color, and position of the title.
Customize the Legend
The legend helps identify the categories displayed in the Doughnut chart.
You can customize the legend position, font size, style, and color using the available settings in the Format visual pane. You can also turn off the legend if the chart labels already provide sufficient category information.
In this example, the legend is positioned at the top right of the visual.
Customize the Slices
Each segment of a Doughnut chart represents a category.
You can customize the colors of the individual segments using the available color settings in the Format visual pane.
Customize Detail Labels
Detail labels display additional information about the categories represented in the Doughnut chart.
Depending on the available settings, labels can display category information, values, or percentages. However, displaying too many labels can make the chart difficult to read.
Adjust the Rotation
The Rotation setting changes the starting position of the Doughnut chart segments.
Adjusting the rotation can help improve the visual arrangement and emphasize specific categories.
Adjust the Inner Radius
The Inner radius setting controls the size of the blank space in the center of the Doughnut chart.
Increasing or decreasing the inner radius changes the thickness of the Doughnut chart segments.
Step 5 Save the visual
Finally, your Doughnut chart is ready. Save the Power BI report to preserve the visual and its formatting.
When to use Doughnut Chart?
Doughnut charts are useful when you want to show how different categories contribute to a whole.
They are most effective when displaying a small number of categories and comparing the proportion of each category to the total. Microsoft categorizes pie and donut charts as visuals for showing the relationship of parts to a whole.
Pros
- Provides an easy-to-understand representation of parts of a whole.
- Helps compare the contribution of different categories to the total.
- Works well with a small number of categories.
- Provides a blank center that can offer space for a label or icon.
Cons
- A large number of categories can make the chart difficult to read.
- Comparing similar-sized segments can be difficult.
- Multiple Doughnut charts can be difficult to compare because segment angles and proportions vary.
- Too many data labels can overcrowd the visual.
Conclusion
Doughnut charts are useful for showing how individual categories contribute to a whole. Their circular design and blank center provide a simple and visually appealing way to display part-to-whole relationships.
Doughnut charts are most effective when used with a limited number of categories. Selecting appropriate data, labels, and formatting options helps create a clear and easy-to-understand visual.
