Radar Chart #

Introduction #

The Radar Chart compares multiple datasets on a polar plot, with each dataset represented as an axis and the peak value of that dataset over the selected time range plotted as its radial position. The connected points form a filled polygon, making it easy to compare the relative magnitudes of several signals at a glance.

Features #

  • One axis per dataset, with custom or overridden axis labels
  • Plots each dataset’s maximum value over the selected time range
  • Automatically closes the polygon for a continuous filled shape
  • Optional fixed radial range (rangeMin / rangeMax) for stable cross-period comparison
  • Optional date selection control
  • Configurable auto-refresh via updateFrequency
  • Configurable height and dynamic-height support
  • Copy chart to clipboard from the mode bar
  • Optional custom trace name for the legend

Use Cases #

  • Comparing peak loads across multiple equipment groups or assets
  • Visualizing a multi-dimensional KPI profile in a single shape
  • Highlighting imbalances between several related metrics
  • Benchmarking current period peaks against fixed reference bounds
  • Quick visual diagnostics across several sensors or signals
