t is not the same as sweeping a source. For that he wants. .dc dec I1 100p
100m 10 which DC sweeps current I1 logarithmically from 100pA to 100mA with 10 steps per decade. This generates a single curve. Your ridiculous comman d would produce a gazillion curves.Almost as useless as this one, which at least illustrates difference in use of sweep and step.

Must be no temp dependence in the NPX 2n3904 model because it doesn't budge . Technically you just add and select I1/Ib(Q1)-1 in Visible Traces box. The heap of junk doesn't respond to the plot directive. Heck it doesn't even ge t the horizontal scale right half the time, tries to take log of 0. Then it intermittently hangs during the simulation but runs fine other times. Dunn o who uses this program.
