I have a lot of dummy load and i would make a graph to compare the return loss of all.
With my older miniVNA i can get the data for each one because with VNAJ i can get out directly the return loss data.
Next the return loss data of all DUT will all be imported with a libreoffice calc spreadsheet.
I make the graph importing the spreadsheet in Qtiplot (this because QtiPlot is more useful to customize the graph).
How can I do all this with nanovna?

P.s. Apologize me for my poor English...

IZ5GVP,
Go to this link for a list of NanoVNA programs that will allow you to plot and save return loss, VSWR and impedance data for your dummy load.

NanoVNASharp
- This is a Windows executable. My advice is to use QRP's Ver 3 MOD. Search this group to find his latest version.

NanoVNA Saver
- Written in Python and will run on Linux or Windows. Can't go wrong with this one.

TAPR VNA
- This is a Windows executable. Harder to configure and get running.

NanoVNA-Web-Client
- My advice is to only use this if you want to save data from an android tablet or phone.

Hmm, that wants updating.
Latest versions should be linked in Wiki main page

First step is to saving S1p and S2p Files:
Yes you can do a lot with SP1 Files. The following software allows directly reading:
SWR - Standing Wave Ratio
Rs - Resistance, series form
Xs - Reactance, series form
Zmag - Impedance magnitude
Theta (deg) - Impedance angle
Rho (mag) - Reflection coefficient magnitude
RL (dB) - Return Loss, plotted as a negative number to show "reverse" scale (see note below)
Phase (deg) - Reflection coefficient angle
% Reflected Power
Q - Quality factor, |Xs| / Rs
Rp - Resistance, parallel form
Xp - Reactance, parallel form
Ls (?H) - Equivalent inductance for series Xs, both positive and negative
Cs (pF) - Equivalent capacitance for series Xs, both positive and negative
Lp (?H) - Equivalent inductance for parallel Xp, both positive and negative
Cp (pF) - Equivalent capacitance for parallel Xp, both positive and negative
