Hi to everyone! This is my first topic so I hope to be in the right forum section.
This is my question:
I have collected data for Impedance Spectroscopy (EIS) so i need to plot the relative Nyquist graph (Zreal vs Zimg). I attach a screenshot of the Nyquist diagram using the Gamry software.
Once I import the data in Origin, is there a method to fit the curve?

Thanks!!
