[Question] Radiation pattern

Hi,

I want to have scale in my radiaton pattern like here:

Which value I should to inscribe:

?

cosidering the pattern on the azimuth direction, the setup would be:

phi -- start 0, stop 360, step 10
theta -- start 0, stop 90, step 90.

while drawing the far-field radiation pattern, be sure that in trace tab: ang is phi (all) and in families tab select available variation theta equals 90.

if the pattern is in elevation direction, just interchange phi and theta.
