Radar chart

A React component in Beamline's Charts & data-vis category.

A few series compared across the same five to eight dimensions as polygons on a polygon or circle grid; hover or arrow keys pick a dimension and read every series' value there.

Use it for

  • Profiles across five to eight dimensions (product scorecards, skill profiles).

Not for

  • Precise comparisons or many series (bar-chart).
  • Dimensions with different units (normalise first, or use a table).

Anatomy

  • title
  • legend (toggle buttons)
  • grid (rings and spokes)
  • axis labels
  • series polygons with points
  • readout for the active dimension
  • table button

Variants

  • 0: grid: polygon · circle
  • 1: fill: gradient · solid · none
  • 2: dots

States

  • loading (skeleton)
  • empty
  • missing value (the outline breaks into a dashed bridge; readout and table say Not measured)
  • series hidden from the legend
  • active dimension
  • table view

Keyboard

  • Tab focuses the plot; ←/→ move the active dimension, Escape clears
  • Legend buttons toggle series (aria-pressed)
  • The table button switches to a table of every value

Motion

Polygons grow from the centre once (500 ms); the active spoke and points brighten. Nothing moves under reduced motion.
