ABSTRACT
A radar graph provides a suitable presentation when the performance of one group on several variables is to be compared with another group. As many axes are drawn as the number of variables, and a polygon is drawn according to the values as shown in Figure R.1. You can see that this looks like a radar. The larger the number of variables, the bigger the radar should be so that all axes can be clearly seen. This depiction seems most appropriate for four to eight variables.
