Compass Labels on Polar Axes

This example shows how to plot data in polar coordinates. It also shows how to specify the angles at which to draw grid lines and how to specify the labels.

Plot data in polar coordinates and display a circle marker at each data point.

theta = linspace(0,2*pi,50); rho = 1 + sin(4*theta).*cos(2*theta); polarplot(theta,rho,'o')

Usegcato access the polar axes object. Specify the angles at which to draw grid lines by setting theThetaTickproperty. Then, specify the label for each grid line by setting theThetaTickLabelproperty.

pax = gca; angles = 0:45:360; pax.ThetaTick = angles; labels = {'E','NE',“N”,'NW','W','SW','S','SE'}; pax.ThetaTickLabel = labels;
