graph to equation

Hi

I have found out the impedance graph of monopole antenna on two plates(plates r 90 deg) by moving it frm center towards edge by a simulation software..I need to write a equation for that graph so that i can use this equation to get impedance graph without simulating for different plate dimension..

I don no how to strat this ?? is their any procedure to do it??r i need to for error n trial method..PLZ help me..
