Suppose you have the data in a matrix A, each row representing a measurement. The day would be in the first column and the direction of the wind in the sixth column. Then you can do:
plot(A(:,1),A(:,6));
set(gca,'YLim',[0,360]); % Range of angles
set(gca,'XTickLabel',[]);
for ind=1:size(A,1),
text(A(ind,1),-25,num2str(A(ind,1)),'Rotation',45,'VerticalAlignment','middle','HorizontalAlignment','center');
end
