MATLAB: Change aspect on polar plot

polar plot

I want to make a polar plot from azimuth angles and zenith angles. I wonder in polar(theta,rho) if theta is azimuth and rho is zenith? and if they must be in radian? I also wonder how I can put change the position of the origin (0) on the circule as I want the origin to start from north and increse clockwise. I appereciate your help.

I found the answer on http://www.mathworks.com/matlabcentral/newsreader/view_thread/134222. I should use view(90,-90).

MATLAB: Why cant i rotate the 2nd line at the X axis it takes reference as point 0,0 and rotates at 45 degree angle i want to rotate the line at same axis

It is rotating. Look at the top of your plot.

The way to rotate relative to a point is to subtract the coordinates of the point to rotate around, do the rotation, then add the coordinates of the point to rotate around back in. If you want ot rotate around (800,0) then cart2pol(x1-800,y1) and plot(x1r+800,y1r)

MATLAB: I have a phase angle at some amplitude, Please check the image i attached , why is it not getting plotted at particular Angle? I have pasted the code as well,,,anyone help

It is plotting correctly (the red dot at about 80°) if ‘phase’ is actually in radians. If it’s in degrees and you want to convert it to radians, do the conversion first:

phase = 26.52867848;
amp = 0.463647609;
theta_rad = phase*pi/180;               % Degrees-To-Radians
polar(theta_rad, amp, 'r.')
