What is a Radar Chart? Explained with Examples

“What is a Radar Chart and is it the same as a Spider Chart? Can I use it to compare multiple variables in one place instead of a table?”

If you have a similar question about radar charts, then you have certainly come to the right place. Known by different names such as web, polar, star, or spider charts, these diagrams help up depict a complex piece of information in a simpler manner. They are also extremely useful in comparing two or more entities on the basis of several parameters in a visually appealing way. In this post, I will make you familiar with the concept of a radar graphic with different examples and would also teach you how to create stunning spider graphs as well.

What is a Radar Chart?

A radar chart is an informative visual tool in which multiple variables (three or more) and compared on a two-dimensional plane. For this, we will create different axes emerging from a common central point. In most of the cases, all the axes are equally distributed and uniformly drawn from each other. Sometimes, the axes are also connected to each other to form different grids that make it easier for us to plot the spider chart.

The radar graph concept was first introduced in 1877 by Georg Mayr and it has been changed vastly in the modern times. These days, web/spider graphs are commonly used in comparison, analysis, and decision-making. Radar charts are considered as a better alternative to column charts as they can depict multiple variables easily without creating a clutter.


When to Use a Radar Chart?

Ideally, a spider (radar) chart can be used in any situation when you need to represent multivariable information in a 2D plane. Though, the concept of a radar graph is mostly used in these cases:

  • Comparison of entities: A spider graph can help us compare different products and concepts in a single diagram. We can distinguish different entities through color- coding.
  • Analysis: A radar chart can also help us understand a concept and how its value is changed over different parameters. For instance, you can analyze the market performance of a product over time.
  • Decision-making: Since a spider chart can depict so much information in one place, it can help you make data-driven decisions easily.
  • Other applications: Apart from that, a radar graph can also work as an ideal visual aid. It can play a vital role in different sectors like marketing, analysis, sales, research, education, and more.


Pros & Cons of Radar Charts

Just like every other visual tool, radar charts can also have certain advantages and limitations. If you want to learn more about the concept of a radar graph, then you should know its pros and cons.


  • It acts as an excellent tool to compare different entities easily.
  • Even if there are multiple variables to compare, we can do it with a spider graph.
  • They are simpler to understand by the audience instead of a column diagram.
  • We can distinguish different entities via color- coding.
  • Extremely useful in drawing comparisons on the basis of different parameters



  • If there are a lot of variables to compare, then even a radar chart can get cluttered.
  • Sometimes, users find it hard to come up with an ideal data set to represent different variables together.
  • They are not ideal for making trade-off decisions or comparing vastly distinctive variables.
  • At times, the radial distance can be hard to judge and provide on-point information.


Elements of Radar Charts

While a spider chart can seem a bit complicated at times, it is pretty easy to understand as it has a few basic elements.

  • Center point: This is the core of a spider chart (at the center) from which different axes are drawn.
  • Axis: Each axis represents a variable in a radar chart and is given a name and different values. A radar graph has at least 3 axes.
  • Grids: When axes are linked in a spider chart, it divides the entire graph into different grids that help us represent information in a better way.
  • Values: Once the graph is drawn, we represent various values on each axis and plot the chart for every entry by allocating distinctive colors.

Radar Chart Examples to Learn From

To help you further understand the concept of radar charts in a better way, I have listed these diverse examples that you can quickly go through.

1. Garden Center Sales Chart

This is one of the simplest spider charts on how a single entity can be represented. In this, we have explained the weekly sales figures of a garden center with the axes varying from 0 to 100. Different variables are shrubs, trees, flowers, bulbs, and seeds. Lastly, we have depicted how many of these variables are sold in a week (for instance, 80 flowers and 60 shrubs).

2. Competitive Analysis Spider Chart

As stated above, radar charts are mostly used in competitive analysis and this is an ideal example of the same. Firstly, the chart is created to represent different parameters like price, durability, after-sales service, advertisement, and so on. Later, three different products are compared on the basis of these variables. For better understanding, each product has been allocated a different color.

3. Employee Performance Chart

In this example, you can see how the overall performance of two employees is compared using a spider graph. To compare them, we have used variables like punctuality, communication skills, technical knowledge, teamwork, etc. Furthermore, both the employees are allocated points (1-5) for each of these variables and are compared accordingly.

Tips on Drawing Stunning Radar Charts

To come up with better radar charts, you can follow these quick suggestions:

  • Try not to represent more than 15 variables in a single chart else it can clutter the diagram.
  • Have all the axes equally distributed unless stated otherwise
  • If it is a comparative chart, then try not to go overboard and keep things simpler.
  • Try to have a common and feasible scale to measure all variables.
  • You can have different color codes to distinguish the entities on the same scale.

That’s a wrap, everyone! I’m sure that the guide would have helped you know more about radar charts and their diverse use. To further help you, I have also come up with some radar graph examples that you can learn from. Though, if you wish to create engaging spider charts on your own, then just take the assistance of EdrawMax Online.
