New donut charts

The new donut charts display data as proportional slices of a circle, where each slice represents a category’s share of the total. Donut charts use the same layout with a hollow center, which can be used to display a summary value or label.

These charts are best suited for showing part-to-whole relationships when there are a small number of well-differentiated categories.

Pie and donut chart example

Your search needs at least one attribute and one measure to be represented as a pie or donut chart.

New features

  • Switch between pie and donut display styles within the same chart configuration

  • Faceting support: When an attribute is added to the trellis section, the chart generates small multiples — one pie or donut per attribute value.

  • Color slicing support to distinguish categories within slices

  • Values chip can be added as the last attribute chip in all the above cases

  • Case: 1 attribute + 2 measures

    • Creates 2 concentric donuts - one for each measure

  • Case: N attributes + 1 measure

    • Creates faceted donuts

    • The last attribute is used to create arcs for the pies

    • Other attributes are used to create facets

  • Case: N attributes + 2 measures

    • Creates faceted concentric donuts

    • The 2 measures are used to create 2 concentric donuts

    • Last attribute is used to create arcs

    • Other attributes used to create facets

  • Case: Values chip + N measures

    • Creates a single donut chart with arcs as different measures

    • Example: A donut showing split of M1,M2,M3 …

Value chips in category

val chips cat1
val chips cat2

Radius control

rad control 1
rad control 2

Pie mode (set inner radius to zero)

pie inner rad 1
pie inner rad 2

Trellis by an attribute

trellis at 1
trellis at 2

Limitations

  • Pie and donut charts are best used with a small number of categories. A large number of slices reduces readability significantly.

  • Multivariate mode is not supported for pie and donut charts.
