Visualize multivariate information utilizing a radar chart in Amazon QuickSight



At AWS re:Invent 2022, we introduced the overall availability of two new Amazon QuickSight visuals: small multiples and textual content containers. We’re excited so as to add one other new visible to QuickSight: radar charts. With radar charts, you may evaluate two or extra objects throughout a number of variables in QuickSight.

On this submit, we discover radar charts, its use instances, and find out how to configure one.

What’s a radar chart?

Radar charts (also called spider charts, polar charts, internet charts, or star plots) are a option to visualize multivariate information just like a parallel coordinates chart. They’re used to plot a number of teams of values over a number of frequent variables. They do that by offering an axis for every variable, and these axes are organized radially round a central level and spaced equally. The middle of the chart represents the minimal worth, and the sides signify the utmost worth on the axis. The information from a single statement is plotted alongside every axis and related to kind a polygon. A number of observations will be positioned in a single chart by displaying a number of polygons.

For instance, contemplate HR desirous to evaluating the worker satisfaction rating for various departments like gross sales, advertising and marketing, and finance in opposition to varied metrics equivalent to work/life steadiness, range, inclusiveness, development alternatives, and wages. As proven within the following radar chart, every worker metric types the axis with every division being represented by particular person sequence.

One other efficient means of evaluating radar charts is to match a given division in opposition to the common or baseline worth. As an illustration, the gross sales division feels much less compensated in comparison with the baseline, however ranks excessive on work/life steadiness.

When to make use of radar charts

Radar charts are an amazing choice when house is a constraint and also you wish to evaluate a number of teams in a compact house. Radar charts are greatest used for the next:

  • Visualizing multivariate information, equivalent to evaluating automobiles throughout completely different stats like mileage, max pace, engine energy, and driving pleasure
  • Comparative evaluation (evaluating two or extra objects throughout an inventory of frequent variables)
  • Spot outliers and commonality

In comparison with parallel coordinates, radar charts are preferrred when there are a number of teams of things to be in contrast. You also needs to be aware of not displaying too many variables, which might make the chart look cluttered and troublesome to learn.

Radar chart use instances

Radar charts have all kinds of trade use instances, a few of that are as follows:

  • Sports activities analytics – Examine athlete efficiency throughout completely different efficiency parameters for choice standards
  • Technique – Examine and measure completely different know-how prices between varied parameters, equivalent to contact heart, claims, huge claims, and others
  • Gross sales – Examine efficiency of gross sales reps throughout completely different parameters like offers closed, common deal measurement, web new buyer wins, whole income, and offers within the pipeline
  • Name facilities – Examine name heart workers efficiency in opposition to the workers common throughout completely different dimensions
  • HR – Examine firm scores when it comes to range, work/life steadiness, advantages, and extra
  • Consumer analysis and buyer success – Examine buyer satisfaction scores throughout completely different elements of the product

Completely different radar chart configurations

Let’s use an instance of visualizing workers efficiency inside a staff, utilizing the next pattern information. The objective is to match worker efficiency based mostly on varied qualities like communication, work high quality, productiveness, creativity, dependability, punctuality, and technical expertise, ranging between a rating of 0–10.

So as to add a radar chart to your evaluation, select the radar chart icon from the visible selector.

Relying in your use case and the way the info is structured, you may configure radar charts in several methods.

Worth as axis (UC1 and a couple of tab from the dataset)

On this state of affairs, all qualities (communication, dependability, and so forth) are outlined as measures, and the worker is outlined as a dimension within the dataset.

To visualise this information in a radar chart, drag all of the variables to the Values subject nicely and the Worker subject to the Colour subject nicely.

Class as axis (UC1 and a couple of tab from the dataset)

One other option to visualize the identical information is to reverse the sequence and axis configuration, the place every high quality is displayed as a sequence and staff are displayed on the axis. For this, drag the Worker subject to the Class subject nicely and all of the qualities to the Worth subject nicely.

Class as axis with coloration (UC3 tab from the dataset)

We will visualize the identical use case with a distinct information construction, the place all of the qualities and staff are outlined as a dimension and scores as values.

To attain this use case, drag the sphere that you simply wish to visualize because the axis to the Class subject and particular person sequence to the Colour subject. In our case, we selected Qualities as our axis, added Rating to the Worth subject nicely, and visualized the values for every worker by including Worker to the Colour subject nicely.

Styling radar charts

You may customise your radar charts with the next formatting choices:

  • Collection model – You may select to show the chart as both a line (default) or space sequence

  • Begin angle – By default, that is set to 90 levels, however you may select a distinct angle if you wish to rotate the radar chart to higher make the most of the obtainable actual property

  • Fill space – This selection applies odd/even coloring for the plot space

  • Grid form – Select between circle or polygon for grid form


On this submit, we checked out how radar charts can assist you visualize and evaluate objects throughout completely different variables. We additionally discovered in regards to the completely different configurations supported by radar charts and styling choices that can assist you customise its appear and feel.

We encourage you to discover radar charts and depart a remark along with your suggestions.
