Re: NanoVNA-Saver 0.1.3
Thanks for the confirmation on this and for looking into it Rune; Auto-scaling should fit the min/max data limits within a margin (to accommodate occaissional min/max overshoot) of the boundaries

Re: gnuplot for nanoVNA Touchstone files
Well, NanoVNA-Saver has a native .exe build that should run fine on Windows 8.1. It wouldn't need any Python prerequisites, at least. :-) Of course, if the exercise is to do things yourself, that's a

Guidelines for SWR 1:1.5 and 1:2 in SWR graph
Is it possible to get distinguishable guidelines for SWR 1:1.5 and 1:2 on SWR graph? That would be very helpful for visualization of SWR measurements (acceptable SWR bandwidth for example).

Re: gnuplot for nanoVNA Touchstone files
If you just want Touchstone files, NanoVNA-Saver was actually, as the name implies, built to save Touchstone files. ;-) Not easily automated, though it probably wouldn't be a huge effort to build a

Re: gnuplot for nanoVNA Touchstone files
nanoVNA shell commands `frequencies` and `data` naturally return columns of numbers, so nearly Touchstone format. The unix utility `paste` trivializes combining text file columns, and while it is not

Re: Abbreviated documentation for more simplistic tasks?
An excellent idea. Someone new to VNA's and what a complex impedance is will be overwhelmed if told to check the wiki, all the forum posts, and read some Agilent document. They just want to measure
