Radial/radar graphs

Radial/radar graphs are sometimes called rose charts. They have a central point from which data radiates outwards.

Data can be plotted as points along a line, where all points are joined up to form a shape. It could also be plotted as segments along a line. Wind speed and direction is often shown as a radial graph. Radial graphs can show lots of different data and do not have to involve compass points.

A radial chart is a graph with many axes coming out from a central point. Many lines in different colours can be drawn with a key to show what the lines mean.

When interpreting radial graphs, you should include:

  • the most common and least common direction
  • a comparison of different directions
  • any anomalies

NB: When interpreting data in any graph, table or diagram you must describe them fully and quote figures to back up your point.
