Hi All,

I havea vector that contains orientaiton of rivers in an area, I want to show it in a plot like a rose plot (like a wind rose, but I just have orientaiton). The data range in degrees is form zero to 178. I used "rose" funciton in matlab, but seems it just gives the distribution of the data! because data are all over the circle! Any idea that I can show the orientaiton of the rivers in my study area in a plot (pereferably rose plot with zero as North) will be greratly appreciated!

Here is a part of data and the result using rose function in Matlab!

A=99.1862290400000

102.281400300000

97.1587243900000

97.3460346000000

104.227574300000

88.7849901300000

24.4667641000000

94.9823140300000

118.183307900000

94.1097181600000

97.1967073000000

Try this:

A = [99.1862290400000
281400300000
1587243900000
3460346000000
227574300000
7849901300000

1967073000000
312991700000
797621500000];
figure
polarplot([A, A]'*pi/180, [zeros(size(A)), ones(size(A))]');
set(gca, 'ThetaZeroLocation','top', 'ThetaDir','clockwise')

Not entirely sure what you're after, is it something like:

A = [99.1862290400000
281400300000
1587243900000
3460346000000
227574300000
7849901300000
4667641000000
9823140300000
183307900000
1097181600000
1967073000000
312991700000
797621500000]; %demo data
Arad = deg2rad(A);
polarplot([Arad, Arad]', repmat([0; 1], 1, numel(A)));
set(gca, 'ThetaZeroLocation', 'top');
