As such, there is no R/X chart. Using the Smith Chart and the cursors, you
can read the R ¡À jX at the top of the screen at the frequency of the
cursor. The complex impedance can be expressed either as R ¡À j X in ohms
or R (ohms) ¡À the actual reactance of the complex portion of the impedance
at the cursor frequency in uH (+) or pF (-).
The RigExperts and the NANOVNAs are ball parks apart from eachother.

SWR is fine, but I can't see anything online about an R/X chart (similar

that available on the RigExpert).
Can I do this on the NanoVNA V4?
On the NanoVNA-H4 you have to plot R and X using a separate trace for
each. However you can plot R and X on the same graph using RigExpert's
AntScope 2 program which does interface to a NanoVNA-H4. Or you can use
the NanoVNA Saver program. Here is an annotated plot from NanoVNA Saver of
a 2M dipole
