EIS Spectrum Analyser
The impedance data can be exposed in Nyquist (default) and Bode coordinate systems in the Impedance Spectra panel.
Graph / ImZ/ReZ - switch from Bode plot to Nyquist plot
Graph / |Z|/Freq and Graph / Theta/Freq - switch from Nyquist plot to one of the two parts of Bode plot.
Clear Graph clears the plot from the impedance spectrum panel.
