Radar charts in Tractorscope

Radar charts compare multiple values around a shared circular axis. They are useful when viewers need to compare patterns across the same set of categories rather than inspect exact values in a table.

When to use radar charts

Use radar charts for:
  • Scorecards with the same dimensions across teams, products, regions, or customers
  • Multi-metric comparisons where the overall shape matters
  • Capability, quality, risk, or performance profiles
  • Comparing a small number of series across a fixed set of categories

SQL shape

Return one column for the radar category and one or more numeric columns for the values to plot.
select
  dimension,
  current_score,
  target_score
from product_scorecard
order by display_order
select
  dimension,
  current_score,
  target_score
from product_scorecard
order by display_order
You can also return a category, series, and value shape when each series should appear as a separate radar polygon.
select
  dimension,
  team_name as series,
  score as value
from team_scorecard
order by display_order, team_name
select
  dimension,
  team_name as series,
  score as value
from team_scorecard
order by display_order, team_name

Settings to review

Radar charts support settings for:
  • Polygon or circular grid style
  • Radial lines and radius axis visibility
  • Axis and radius value formatting
  • Custom axis minimum and maximum values
  • Normalized data
  • Fill opacity, stroke width, dots, and dot size
  • Labels, legends, tooltips, animation, and chart colors

Tips

  • Keep the number of radar dimensions small enough to scan.
  • Use a consistent category order across dashboards.
  • Use custom axis bounds when viewers need comparable scales across charts.
  • Use bar or table charts when exact rank or precise value comparison matters more than the overall shape.
