Click here to access Google Drive to download the template for the Polar Area Diagram.
The template is for 2 to 12 wedges, but note that not all wedges start from zero degrees. The number behind the decimal point in the file names represents the starting angle. Hence, the pie chart method of labelling mentioned in my previous post cannot be used. Nonethelss, from the previous post, you already know how to create your own wedges for a Polar Area Diagram (Rose / Coxcomb Chart) on Tableau, so try it out!
