Plot Impedance Diagram from values

I have a set of 50 Hz Voltage and Current values stored as arrays under variable name 'Volt' and 'Cur' sampled at 1000 Hz. How can I plot the impedance diagram (R+jX) from these? Thanks

From what I understand is that you have complex valued Voltages(Volt) and Currents(Cur). To get the impedance value for a particular value of voltage and current, the following relations will hold.

R = real(Volt/Cur);
X = imag(Volt/Cur);

Now to get the impedance diagram you just need to plot the data obtained above in appropriate axes.

Let me know if this is what you intend to do.

No we can plot them directly. The issue is to do an fft on a 20 ms window and then plot the same.
