The data of the selected time period is categorized by peak wave direction and
significant wave height.
The length of a petal (or a portion of the petal), corresponds to the
frequency of occurrence.
The peak wave direction categories (degrees clockwise from True North):
11.25 - 33.75 (centered at 22.5)
33.75 - 56.25 (centered at 45.0)
56.25 - 78.75 (centered at 67.5)
...
349.0 - 11.5 (centered at 0.0)
