Show wind frequency.
Show wind speed.
Show wind energy.
For each of the sectors the outermost (blue) wedges show the
wind frequency distribution.
The
middle (black) wedges show the distribution of the product of
the two columns, i.e. the wind speeds times their frequency.
The
innermost (red) wedges show the distribution of the wind speeds
cubed (i.e. the energies) multiplied by their frequencies.
