What is a Radar Chart?
A radar chart refers to a graphing method of data in a two-dimensional diagram when dealing with multiple data variables. You can use the chat when you want to graph a single group of data variables or when you want to compare multiple data groups that originated from the same data variable. When graphing the data points, you need to ensure that they all originate from the central data point. Gridlines are used when you want to connect the axes on the graph, making it easier to read.
When you connect all the data groups outlined on the chart, they form a polygon. When comparing more than one data group of the same chart, you need to utilize different colors to make them different from one another. Considering the structure of a radar chart, it also has other names such as a spider chart, web chart, polar chart, or star plot. When all the data points are connected on the chart, you can easily translate the data outcomes and make reliable conclusions.
The Application of Radar Charts
Radar charts are applied in different scenarios across industries. They are mostly used to achieve a specific type of data comparison, depending on your personal preference.
