Details:

Compass plot does not show angles on axis but when code is run in matlab it
does show the angles on the axis.


clear all,clc
x_angle=[45,90,123,43,53,23,53,12];
y_amp=[1,.5,.4,.1,.6,.3,.7,.3]; 
%[x,y]=pol2cart([45 90]*pi/180,1);
[x_cart,y_cart]=pol2cart([x_angle.-180]*pi/180,y_amp);
h = compass(x_cart,y_cart);

for k = 1:length(x_cart)
    a_x = get(h(k), 'xdata'); 
    b_y = get(h(k), 'ydata'); 
%To delete the arrows you need to delete all but the first two entries in the
xdata and ydata fields of the plot. The color can be changed by setting the
color property. Please find below a solution for compass plots with arbitrary
numbers of arrows.
    set(h(k), 'xdata', a_x(1:2), 'ydata', b_y(1:2), 'color', 'r')
end;
