Circular time plots using polarhistogram?

Hi there,
I don't know how to make circular plots in Matlab. They can provide insight into patterns of activity based on time of day and are frequently used in research articles (like the attached figure). Is it possible to use polarhistogram to draw it? Thanks for your comments and suggestions!

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!
