The color coding for each beer helps to visually correlate and contrast the beers over its diverse aspects. They are drawn in R using the fmsb library.. Select the same data that you selected before we created the radar chart again. It is a web-shaped diagram used to indicate the relative influence of different numerical parameters. The idea is that by plotting a value along each axis and then connecting up the resulting points a shape forms. Radar Charts Radar Charts are used to compare two or more items or groups on various features or characteristics. Which categories are lacking? Radar Chart – This is a basic radar chart and it displays values that are relative to the central point. All of the websites mentioned in the previous section as sources for radar do not use smoothing algorithms. The relative position and angle of the axes is typically uninformative.
