I have spherical data consisting of the amplitude or radius as a function of theta and phi, i.e: R(theta,phi). I want to plot this data as a surface or contour. I tried the polarplot3D function from the File exchange and it didn't give me the results for which I was looking. I then attempted to convert from the spherical coordinates to cartesian coordinates, but the plot looked just like the plot output from the polarplot3D function (surf(X,Y,R) The data rotates about the Z axis correctly, like the azimuth (phi) is being plotted polarly, but the surface sits above the xy plane, i.e. the elevation (theta) isn't being plotted polarly. I want every value in R to be plotted as the amplitude of a radius from the origin. I haven't yet attempted to
