Suppose you have the wind direction in degrees at 1 minute intervals for 1 day:
windDir=360*rand(1,1440);
Make a histogram of the wind:
polarhistogram(windDir)
Maybe you don;t like that histogram because the degrees do not look like a compass. Suppose also that you want the histogram to have 15 degree segments (pi/12) instead of 30 degrees. Make those fixes as follows::
figure; polarhistogram(windDir, 'BinWidth',pi/12)
set(gca,'ThetaZeroLocation','top','ThetaDir','clockwise');
Good luck!
