An alternative could be to use the bar chart’s funky little sister, the lollipop chart (Figure 2A). It’s easy and free to post your thinking on any topic. In short, radar charts contradict one of the most basic data visualization rules: don’t connect categories with lines. Acknowledgements: Thanks to Valérie Milner for copyediting my poor English writing. This makes them useful for seeing which variables have similar values or if there are any outliers amongst each variable. But a more significant problem emerges when one realizes that in most cases, the order of the categories is arbitrary and that different sorting options may result in entirely different visual pictures.

Radar Charts are a way of comparing multiple quantitative variables. But if one prefers radial charts, another option is to use small multiples next to one other, while keeping categories unmoved and the minimum and maximum of the y-axis constant. They can sometimes be an alternative to line charts, and are useful for overlaying and comparing data that have multiple variables.

Radar charts are considered as a better alternative to column charts as they can depict multiple variables easily without creating a clutter. Now select the new tabular data and create a regular radar chart with area. Admittedly, they also have their own limitations, just like any other chart. With a continuous dependent variable and a categorical independent variable, a bar chart is undoubtedly the most common option. With these limitations in mind, I’ll then present four alternatives. Finally, Figure 2D shows a fourth option which, so far, is also my favorite one. I will thus refer to this one as the stellar chart. Because petal chart is nothing but a tweaked radar chart.

The same transformation can be applied to lollipop charts, resulting in Figure 2C, which could be called a radial lollipop chart. Alternatives to radar charts Radar charts are often used to compare different profiles. But what if we noticed something interesting about the differences between A and B groups? Nevertheless, radial column charts, radial lollipop charts, and stellar charts certainly offer a good starting point to open a discussion about replacing radar charts. In Petal Charts – an Alternative to Radar Charts I have suggested using a radar chart tweak to replace the radar charts. They are similar to bar charts, except each axis extends out radially from the center of the chart. Let’s say that we conclude that there is no correlation between the two series of data. Just use Radar Chart to solve problems more effectively. Much to my dismay, the names “wind rose charts” and “star charts” are already used for other graphs. Data science, machine learning & data visualization consultant and lecturer, A radar chart (sometimes called “spider charts”) look cool but are, in fact,pretty lame. Radar charts, also called web charts, spider charts or star charts, are often used to display various characteristics of a profile simultaneously. It is very useful for portfolio decisions where you may consider several alternatives and commit to implementing just a few of them based on their relative merits.
