Radar chart

Use a radar chart to compare a compact set of category values around a shared scale.

Every preview on this page is generated from the YAML shown below it using a fixed documentation dataset.

Basic

Use one categorical dimension to create the radar indicators and one measure to set each spoke length.

Key fields

visuals:
  status_radar:
    title: Order status radar
    description: Compares order status counts on a radar chart.
    type: radar
    query:
      dimensions:
        status: orders.status
      measures:
        order_count: null
      sort:
        - field: value
          direction: desc
      limit: 8

Alternate categories

Replace status with delivery buckets to compare a different categorical profile while preserving the same category-value shape.

Key fields

visuals:
  delivery_radar:
    title: Delivery speed radar
    type: radar
    query:
      dimensions:
        delivery_bucket: orders.delivery_bucket
      measures:
        order_count: null
      sort:
        - field: delivery_bucket
          direction: asc

Filled area

Enable presentation.area to emphasize the overall revenue profile across states rather than only the outline between individual values.

Key fields

visuals:
  state_radar:
    title: State revenue radar
    type: radar
    presentation:
      area: false
    query:
      dimensions:
        state: orders.state
      measures:
        revenue: null
      sort:
        - field: value
          direction: desc
      limit: 8

API reference

Kind: chart. Renderer: echarts. Supported result shapes: category_value.

Field	Type	Default	Allowed values	Description
`query.dimensions`	`field mapping`	—	—	Groups query results and supplies category, hierarchy, matrix, graph, or geographic labels.
`query.limit`	`integer`	`no limit`	`positive integer`	Caps the number of rows returned to the renderer.
`query.measures`	`measure mapping`	—	—	Selects the governed semantic measures consumed by the visual shape.
`query.sort`	`sort list`	—	—	Orders query results by a returned field or measure alias.
`presentation.area`	`boolean`	`true`	`true` `false`	Fills the radar polygon so its overall profile is easier to compare.

Accessibility. Use a descriptive title and unit, and do not rely on color alone to distinguish series or values.
