From HFSS, I insert the 3D radiation pattern on the object as shown in the 1st figure. But how can I add the numbers for the radiation as shown in the 2nd figure? I would like have both the radiation and numbers on the object on the same figure. Thanks.
It's done the same way as the second. In the second plot, you didn't select gain, but radiation resistance (?). Select gain dB (total) and plot Phi around Theta.
