How can I rotate the axis for a polar plot?

Hi,

Would anyone know how to adjust (rotate) the polar plot function such that the vertical axis starts at 0 degrees - as opposed to 90?

theta=0:0.1:2*pi;
e=cos(theta);
polar(theta,e);

Kind regards,

See the answer at http://www.mathworks.com/matlabcentral/answers/93690-how-do-i-rotate-or-flip-a-polar-plot which changes the viewpoint specification using view. For your case, you would want to call (after the polar plot has been created)

 view([90 -90])

Use axes properties. To rotate theta = 0 from right side [default] to bottom use following:

set(gca,'ThetaZeroLocation','bottom')
