Circumplex Chart

The Circumplex chart, also known as the Polar Area chart or Nightingale Rose chart, is a combination of the Bar chart and Pie chart. The Circumplex chart can be drawn on a polar coordinate grid. Each category or interval in data is divided into equal segments on the radial chart. The distance of each segment from the center, as per the denoted values, depends on a polar axis. Therefore, each ring from the center of the polar grid can be used as a scale to plot the segment size and represent a higher value.

Each category may have more than one sub-category, where each sub-category is shown by a section of the disc and each section has the same angle. The value of the corresponding sub-category is shown through the area. By changing the radius in a Circumplex chart, the user can adjust the area of each segment (based on data).

Best Situation to Use a Circumplex chart:

  • To display manifold data in the form of a two-dimensional chart of three or more measurable variables represented on axes starting from the same point.
