I have a set of vector data with magnitudes between 1 and 1.08. Using compass, Matlab sets the default radius to between 0 and 1.5, making the differences between 1 and 1.08 indistinguishable. Using rlim does not work as compass uses a cartesian coordinate system. Is it possible to set the radius limits to between 1 and 1.1?

An example dataset: a = 1; b = 1.08; r = (b-a).*rand(50,1) + a; %magnitude

c = 0; d = 2*pi; direction = (d-c).*rand(50,1) + c;

[u,v] = pol2cart(direction,r); compass(u,v)
