What is wrong with my approach to building this histogram?

I am working on a project that builds a histogram based on the data selected by the user in the program. I am facing an issue with how my histogram is built. I use the code below to build it. 'Theta' there is one of the possible data arrays that can be selected. The histogram on the left is built using my approach. However, it should look like the one on the right. What am I doing wrong and how can I revise my approach to building it? Edit: I have to add that 'Theta' contains the azimuth changes of the wind direction measured at a weather station. So I suppose this might play a part why my histogram is not correct.

theta=[236   239   154   237   267   107   102   103    95   104   101   110    94 99    97    97   118   123   115   123    94    96   119   101]
p = polarhistogram(theta,16);
ax = gca;
ax.ThetaLim = [0 360];
ax.ThetaTickLabel = {'E','NE', 'N', 'NW', 'W', 'SW', 'S', 'SE'};
ax.ThetaTick = (0:45:360);

From the documentation for the polarhistogram function: "polarhistogram(theta) creates a histogram plot in polar coordinates by sorting the values in theta into equally spaced bins. Specify the values in radians." [Emphasis added.]

Your theta values look like angles in degrees. Use deg2rad to convert your data to radians.

theta=[236   239   154   237   267   107   102   103    95   104   101   110    94 99    97    97   118   123   115   123    94    96   119   101];
p = polarhistogram(deg2rad(theta),16);
