Very nice wind rose plotter, but with some bizarre behavior regarding the direction.
dtype - 'standard' uses standard mathematical plotting, i.e. 0 degrees lies on the positive x-axis, 90 degrees on the positive y axis.
dtype - 'meteo', which I assume stands for meteorological, uses geographical directions, but 180 degrees out of phase! i.e. 0 is south (when it ought to be north), 90 is west (when it ought to be east). I'm not sure why you'd want that, unless you expect to receive winds based on where they're going and wish to plot them as where they've come from, or vice-versa.
I've edited my copy to read this, at the appropriate place.
% directions conversion:
elseif isequal(dtype, 'meteo')
