RHCP and LHCP polarization of antenna patterns

Hi,

I am trying to write a matlab code to present the antenna pattern results in RHC and LHC polarization.
I have the measured data for ETotal, EPhi and ETheta amplitude and phase for different theta and phi angles.

I can plot the theta and phi polarization of the patterns but not the RHC and LHC polarization.

Thanks,

I don't no if I can use the following formulas or not:
RHC polarization --> 1/√2e^(-jφ)*(θ-jφ)
LHC polarization --> 1/√2e^(jφ)*(θ+jφ)
