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 Linuxu, Windows and Mac OS X **** 
 PRGRAMS: 
** Impedance / admittance measuring (miniVNA)  new version Jul 2011 
** Sweep frequency - wobler (miniVNA)  new version Jul 2011 
** Active / passive filters design  Since May 2011 FILTER fo Mac OS X, too !
          New: HANTEK Oscilloscope DSO-2150 in Linux !!   
          No installation, do drivers! Just unzip and click...
            Version 0.2.2: 15.3.2013 - not only Linux but for Windows also!
