How do you create a Nyquist plot from experimental values of voltage gain and phase shift found in a .csv?

I have experimental values for the voltage gain and phase shift of a LC filter circuit. Is there any way in constructing a Nyquist plot with the experimental values that are located in a .csv file?

Any help would be greatly appreciated!

I understand you have bode plot data in a .csv file which you want to import in MATLAB and from the data you want to obtain the Nyquist plot.

We can read .csv file into a table form using ‘readtable’ command:

To get Nyquist plot, command ‘polarplot’ can be useful:
