Low Priority (at least for me) with 3D Pie Chart

For those of us with fairly variable wind direction, the 3D Pie chart showing wind direction distribution “cuts off” wind directions from the Northwest quadrant. Seems that the size of the chart (and legend) is such that “only” ten wind directions can show (out of 16 possible). For me, WNW is a strong “second place” in terms of wind direction, but WNW, NW, and NNW don’t make it onto the chart legend.

Any way to order the legend based upon the highest percentage of wind distribution?

Maybe this is terribly important to someone else; for me it is a very minor issue that can go to the bottom of your pile, Brian, but thought I’d bring it up. See (I hope) example below:
