How to plot radiation pattern in Labview

Hi anybody know how to plot the radiation pattern from spectrum analyzer on Labview.
I need to measure the radiation pattern for spiral antenna. I made the lab setup with transmitter and receiver with spectrum analyzer, signal generator and PC. The PC which is connected to spectrum analyzer has Labview installed. But I don't know how to use it. I am new to labview and i don't have time to refer Labview manual since i need to finish my experimental within two day. please anyone help me to plot the polar plot in LabView.

Thank you
