❓When to use Radar Plot ?
1. Radar plot for comparison of objects that have many variables
Radar plots are used to display the comparison of one object with another object that has many variables (more than 3 variables). When an object has many variables, it is very difficult to graph the comparison. If we have a dummy dataframe like below, namely the comparison of FIFA 23 stats between Ronaldo and Messi how to make a comparison graph with this dummy dataframe ?
ronaldo
81
92
78
85
34
75
messi
81
89
90
94
34
64
We can try to create a comparison graph like this, using a barplot. But are the results easy to read?
The results of the comparison chart are difficult to read because the barplot itself has a drawback, that is when there are too many variables it is difficult to see it using a barplot
Radar plot can be used to create a comparison graph of an object that has many variables, here are the results of the radar plot for comparison of the data above. The resulting chart is easier to read than using a barplot
2. Radar plots are difficult to read when comparing many objects
Although radar plots are good for comparing objects that have many variables, but radar plots have the disadvantage that when you want to compare many objects (more than 3) graphs will be difficult to see
Here's an example of an improper radar plot by trying to compare 4 objects.
It can be seen that the comparison graph between the 4 objects is difficult to read
Summary
Radar plot is used when the object to be compared has enough variables (more than 3 variables) and the object being compared is not too many (less than 4 objects)
