What is the difference between Nyquist plot and Cole-Cole plot in AC Impedance Spectroscopy?
No, they are "not[1] same". They are, simply[2], very different[3-5] graphical representations of the EIS (same) data.

The relationship obtained between real and imaginary components is represented as a Cole–Cole (Nyquist) plot. The Cole–Cole plot is generally simulated with an equilibrium circuit composed of resistance, capacitance, and sometimes inductance, in which the electrode/electrolyte solution interphase is virtually structured. Therefore, impedance spectrometry can be used for analyzing the state of the electrode surface and the kinetics of the metal hydride electrode.

both are using the real and imaginary part and purpose to proof the semiconducting nature. But Nyquist plots related to the effect of grans and grain boundaries.
I know the Niquist curve can be plotted directly using the impedance (potentiometry) of the autolab. How can I plot the Cole cole curve then? @
