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: Facet is created when attributes are added on the primary axis and trellis are created when an attribute is added to a trellis channel

  • Color slicing support to distinguish categories within slices

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

Changes

Create arcs from measures

You can now create arcs from different measures:

val chips cat1
val chips cat2

Radius control

You have complete control over inner and outer radius to move from Donut to Pie Mode:

rad control 1
rad control 2

Pie mode (set inner radius to zero):

pie inner rad 1
pie inner rad 2

Trellis mode

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.
