Dear Group, I'm trying to export the displayed data with nanoVNAsaver, but

When you file export from NanoVNA Saver you do not get the display graph data.. It is a "touchstone" format file that only gives the S11 (.s1p) and S21 (.s2p) coefficients in complex real + imaginary form. You can import it back into Saver or another program like NanoVNA# to plot the graphs if you need to.
The only way to save the graphs is to right click and save them as a jpeg graphics file.
If you want to get the data vs frequency for parameters like SWR, impedance, return loss etc. you have to import into a spreadsheet and do the calculations yourself. There may be some other program that can import touchstone files and export them as other types of data files but I am not aware of any.
