I would like to plot a wind rose. I used the following code:
rose(A,8); % A is my data
view(90, -90);
But in the resultant wind rose plot the values for all bins are the same. Therefore I think that something is wrong, because in the histogram I see that I have much more data between 150-250 angles than in other angles. Does anyone know what can be wrong? My data are imported as an array, the data are sorted from the smallest to the biggest values.
I would also like to change the start angle for separation of my classes, from:
0-45, 45-90, 90-135, ...,
to
337.5-22.5, 22.5-67.5, 67.5-112.5, ...,

The angle (that appears to be ‘A’ in your code) has to be in radians. So you have to multiply ‘A’ (that seems to be in degrees) by (pi/180).
rose(A*pi/180, B)
