Polar Bar Chart
Tableau Viz Extension
Bars laid out around a circle, so a cyclical pattern reads as a shape instead of a row.
Built for cycles
Sales by hour, incidents by weekday, wind by direction. The first and the last category sit next to each other, which is where the pattern usually is.
Length or area
Choose whether a value drives the length of the sector or its area. Area is the honest default for a Nightingale rose; length is easier to compare.
Labels that stay legible
Values inside the sectors, category labels around the rim, ring values on the scale, each dropped automatically when the space is too small to hold it.
