any info about parametric dc sweep ? for ex: want to plot gm/id vs vgs of a device and vgs is parameter not a voltage source I tried let and alterparam but ngspice gives two errors: 1- vector vgs is not available or has zero length 2- wrong format in alterparam line is there a simpler way to do this sweep ? or what's wrong here ? Thanks all! @Stefan Schippers
