Is it possible to create a polar-like plot or histogram where the theta values are in minutes between 0 and 60?

I can do it by converting the values to radians and setting the labels, but it would be less-error prone if the theta scale was settable (ThetaLim doesn't do this).

WT = [ 1 2 3 5 42 43 59.5 0.5];
theta = deg2rad( WT*6 );
edges = deg2rad(-5:10:355);
figure;
pax = polaraxes;
polarhistogram( theta, edges );
pax.ThetaDir = 'clockwise';
pax.ThetaZeroLocation = 'top';
pax.ThetaTick = [0 90 180 270 360];
pax.ThetaTickLabel = [0 15 30 45 60];
pax.RTick = [];

@dormant, The method you've come up with seems like a good approach.

I think the (accepted) answer does not understood or acknowledge what the expected output is.

在 MATLAB Online 中打开

WT = [ 1 2 3 5 42 43 59.5 0.5];

theta = deg2rad(WT*6);

edges = deg2rad(-0.5:1:60.5);

figure;

pax = polaraxes;

polarhistogram(theta, edges);

pax.ThetaDir = 'clockwise';

pax.ThetaZeroLocation = 'top';

pax.ThetaTick = [0 90 180 270 360];

pax.ThetaTickLabel = {'0' '15' '30' '45' '60'};

pax.RTick = [];

The code snippet provided is a good starting point and, with a few adjustments, it should be able to produce a reliable and accurate clock-like polar histogram plot.
