radial value in polar plot doesn't connect as intended

I want to make a polar plot that connects the radial value of each angle kind of like the attached image.

However when I try to plot it in matlab, the radial value doesn't seem to be connected as desired and the is a value in between the angle which i do not intend. is there anything wrong with my code? thanks

deg=0:30:330;
max=[2 2.14 2 1.86 2.14 2.71 2.54 2.29 2.29 2.43 2 1.86];
min= [2.14 2.57 2.29 2.29 2.43 3 2.86 2.71 2.71 2.71 2.14 2];
polarplot(deg,max)
ax=gca
ax.ThetaZeroLocation='top'
ax.ThetaDir='clockwise'

change degree to radian:

deg=0:30*pi/180:330*pi/180;

polarplot(deg,max)

ah i see. thanks a lot. is there anyway to connect the first and last point?

[Simon Chan]

Just add the first point to the end:

deg=0:30*pi/180:360*pi/180;

max=[max, max(1)];

polarplot(deg,max);

deg=0:30:330;
max=[2 2.14 2 1.86 2.14 2.71 2.54 2.29 2.29 2.43 2 1.86];
min= [2.14 2.57 2.29 2.29 2.43 3 2.86 2.71 2.71 2.71 2.14 2];
polarplot(deg2rad(deg([1:end 1])),max([1:end 1]));       % cycle back to 1st point
ax=gca;
ax.ThetaZeroLocation='top';
ax.ThetaDir='clockwise';
