Donut charts are used to show the proportions of categorical data, with the size of each piece representing the proportion of each category. A donut chart is created using a string field and a count of features, number, or rate/ratio field.

Donut charts can answer questions about your data, such as: What are the proportions of categories to the total?


An insurance company is reviewing the types of policies it offers to compare to the findings from a recently completed market research project. One step in the review is to compare the total value of policies in each policy class. A donut chart can be used to visualize the proportion of total insured value (TIV) in each policy class.

The donut chart above gives a visual representation of each policy class, with the total insured value in the center.

Create a donut chart

To create a donut chart, complete the following steps:

  1. Select one of the following combinations of data:
    • One string field String field
    • One string field String field plus one number Number field or rate/ratio field Rate/ratio field

    If you do not select a number or rate/ratio field, your data will be aggregated and a count will be displayed.

    You can search for fields using the search bar in the data pane.

  2. Create the chart using the following steps:
    1. Drag the selected fields to a new card.
    2. Hover over the Chart drop zone.
    3. Drop the selected fields on Donut Chart.

You can also create charts using the Chart menu above the data pane or the Visualization type button Visualization type on an existing card. For the Chart menu, only charts that are compatible with your data selection will be enabled. For the Visualization type menu, only compatible visualizations (including maps, charts, or tables) will be displayed.

Usage notes

Donut charts are styled by unique values.

Each slice on the donut chart can represent either a count of features in that category or the sum of a number or rate/ratio field. The total of either the count or the specified field is displayed in the center of the donut chart.

This chart type creates a result dataset Results in the data pane, which includes the fields used to create the chart. The result dataset can be used to create additional visualizations, rename the fields on the chart axes or in the pop-ups, or apply filters to the chart.

Use the Layer options button Layer options to open the Layer options pane and update the following configuration options:

  • Use the Legend tab Legend to make selections on the chart. To change the color associated with a value, click the symbol and choose a color from the palette or enter a hex value. The pop out legend button Pop out legend displays the legend as a separate card on your page.
  • Use the Appearance tab Appearance to change the outline color on the chart.

Use the Card filter button Card filter to remove any unwanted data from your chart. Filters can be applied to all string, number, rate/ratio, and date/time fields. A card filter does not affect other cards using the same dataset.

Use the Visualization type button Visualization type to switch directly between a donut chart and other visualizations, such as a unique values map, summary table, bar chart, or treemap.

Use the Sort button Sort to change the sort order of the chart. The chart can be sorted in ascending, descending, alphabetical, or reverse alphabetical order. The default order is Sort descending.

Use the Maximize button Maximize to enlarge the card. Other cards on the page will be reduced to thumbnails. The card can be returned to its previous size using the Restore down button Restore down.

Use the Enable cross filters button Enable cross filters to allow filters to be created on the card using selections on other cards. Cross filters can be removed using the Disable cross filters button Disable cross filters.

Use the Flip card button Flip card to view the back of the card. The Card info tab Card info provides information about the data on the card and the Export data tab Export data allows users to export the data from the card.

Use the Card options button Card options to access the following menu options:

  • Appearance button Appearance—Change the background color, foreground color, and border of the card.
  • Edit labels button Edit labels—Create custom labels for the chart axes. To edit the labels, click the Edit labels button then click the axis to make it editable.
  • Order button Order—Move the card forward or send the card backward relative to other cards on the page.
  • Delete button Delete—Removes the card from the page. If you did not intend to delete the card, you can retrieve it using the Undo button Undo.
