Matlab Fix Compass Axis [closed]

Question

compass(x,y);

How can I fix that 2.5 in this image to say 10.

Answer 1

Here's a workaround: First add a line of constant radius with the limit you want to have and then make it invisible:

Z = eig(randn(20,20));
h = compass(10 * ones(size(Z)));
set(h, 'Visible', 'off')

then add the data you actually want to plot:

hold on
compass(Z)
