Circular barplot | the R Graph Gallery

Step by step

Here is a set of examples leading to a proper circular barplot, step by step. The first most basic circular barchart shows how to use coord_polar() to make the barchart circular. Next examples describe the next steps to get a proper figure: gap between groups, labels and customization.

Most basic

The most basic circular barchart you can build, to illustrate how coord_polar() works

Add labels

Add labels with geom_text(). Tricky, since you have to compute label angles first.

Add a gap

Lear how to add a gap in the circle. The same technique will then be used to add gaps between groups

Gap between groups

The space between groups allows to highlight them.

Order

As usual, it makes sense to order bars of each group to get the ranking more easily

Customization

Add scale, group names and more

Circular Stacked Barchart

Now that all the basic concepts of circularity have been described, it is possible to build a highly customized circular stacked barchart.
