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.

Radar presentation supports area and an optional shared maximum across its indicators. Gauge-only fields such as minimum, target, showPointer, progressWidth, and thresholds do not apply.

Basic

Use one categorical dimension to create the radar indicators and one metric to set each spoke length. Add a second dimension to compare governed series; the first dimension remains the category and presentation.legend controls the series legend.

Key fields

visuals:
  status_radar:
    title: Order status radar
    description: Compares order status counts on a radar chart.
    type: radar
    presentation:
      type: polar
      area: true
    query:
      type: aggregate
      dimensions:
      - status
      metrics:
      - order_count
      sort:
      - field: order_count
        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:
      type: aggregate
      dimensions:
      - delivery_bucket
      metrics:
      - order_count
      sort:
      - field: delivery_bucket
        direction: asc
    presentation:
      type: polar

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:
      type: polar
      area: false
    query:
      type: aggregate
      dimensions:
      - state
      metrics:
      - revenue
      sort:
      - field: revenue
        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 or hierarchy labels.
`query.limit`	`integer`	`no limit`	`positive integer`	Caps the number of rows returned to the renderer.
`query.metrics`	`metric mapping`	—	—	Selects governed semantic metrics consumed by the visual shape.
`query.sort`	`sort list`	—	—	Orders query results by a returned field or metric alias.
`presentation.area`	`boolean`	`false`	`true` `false`	Fills the governed radar area.

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