The radar chart, also known as web chart, spider chart, star chart, star plot, cobweb chart, irregular polygon, polar chart, or Kiviat diagram, commonly used in many domains. Here is in innovative way of using Radar Chart for plotting a multi-dimensional time-series data:
Here a five-dimensional dataset with one-minute sampling time, is used for illustration purposes. The first sample is plotted (a) on the Kiviat plot having a time axis that is normal to the plot plane. The next samples are added as additional Kiviat plots whose planes are parallel to the plane of the first and spaced along the time axis according to the sampling time (b–d). The diagram can be updated by adding such “data slices” in a first-in, first-out manner.
This technique of using Radar Chart for plotting multi-dimensional time-series data was first used by Ray C. Wang, Michael Baldea, and Thomas F. Edgar in their published paper titled Data Visualization and Visualization-Based Fault Detection for Chemical Processes
