Savant uses an Azimuth/Elevation angle convention, but if you want to plot the Phi and Theta gain components you can do that following these steps: -> Select analysis results under the label “Results” in Project tree menu (usually on the left side of Savant GUI); -> Click on “Plot” icon in analysis property panel; -> Select Decibel from Scale options; -> Select Vertical (for Theta Gain component) or Horizontal (for Phi Gain component) from Polarization options. For further information about polarization options please refer to Savant Help page (Help -> Help Contents…).
