Radarchart¶

📖 Options Reference | 👩‍🏫 Tutorials

Purpose & Application¶

The radarchart is the best chart to compare two groups or more on several dimensions at the same time.

It allows you to get an overview of each group scores/performances by comparing their areas, and then to focus on specific dimension of the radar.

📝 For example, evaluate the success of two adverts on the same market metrics (awareness, consideration, purchase).

Use this chart when you want to compare the performances of several entities, on different metrics. It allows you to :

  • Compare the entities between themselves, overall and on a specific metric
  • Compare the metrics, and see where the best/worst scores are obtained

Toucan USP¶

What makes this chart a killer story?

Units and precision give context about the values you are displaying: it is especially useful if you’re comparing metrics which are not straightly related. For example: if you want to compare movies profitability (%), duration (min) and IMDb score (/10) (Internet Movie Database). 🎬

The USA is my top profitability country in 2019, but the IMDb score is only of 6 over 10 which is surprisingly less than the one for France and Japan! And if I have a look at the duration 🕑, movies for the USA is way less longer than France and Japan in average.

Display values to help decision makers focus on what’s important. We know sometimes radarcharts can be difficult to read because of the multiple dimensions that can be displayed.. It allows your users to quickly read and understand this viz! 😎

I want to have a global vision of the movies profitability, duration, and IMDb score for France, right from its opening.

Order your viz to make relevant informations display first: do you want to look for the top movies profitability? 💸 Use labels order to see the best ones displayed in a second.

If everytime I come to see my radarchart I have to turn my head for a while in order to analyze profitability, I need to set-up some specific order. 🤓

Display chart as parallel plot if your users are really not used to reading multidimensional charts, it allows you to show metrics in the same direction and makes easy to compare the shapes of each entities you’re analyzing.

Japan and France have a very good IMDb score with 7 over 10 in 2019! But what is the associated duration and profitability? Thanks to parallel plot ⏸ I can check it at a glance.

Fill series rather than outline to add some colors to your chart 🎨 which can be a great way to highlight a specific entity or the average for example.

I have several countries to compare : Japan, France and the USA, and I want to be able to compare them to the profitability average, duration average and IMDb score average.
