%% Specify theta-Axis Tick Values and Labels % Create a polar plot. Display tick marks and grid lines along the % _theta_-axis at 0, 90, 180, and 270 degrees. Then, specify a label for % each tick mark. theta = linspace(0,2*pi); rho = theta/10; polarplot(theta,rho) thetaticks([0 90 180 270]) thetaticklabels({'East','North','West','South'})
