Do you operate miniVNA for antenna analysing? Or for plotting filter's and amplifier's amplitude characteristics? And you want to display impedances in the Smith chart? Or do you need to construct LC filter? Or perhaps an active filter?
Some utilities and tools are here:

 **** Since July 2011 miniVNA works in Linux, Windows, Mac OS X and since November 2014 on Raspberry Pi **** 
 PRGRAMS: 
** Transmission response (miniVNA)  new version Apr 2017 
** Impedance / admittance measuring (miniVNA)  new version Apr 2017: miniVNA is found automatically 
** Sweep frequency - wobler (miniVNA)  new version Oct 2015 
** Active / passive filters design
** HANTEK Oscilloscope DSO-2150:with original drivers, install shell. Just unzip and click...
