sounds interesting. i'm curious how you did this.

it's probably best to let gnucap choose the step size, and use all
sample points that it has computed internally. so instead of

.tran 0 1 .1  <= do a simulation, force evaluation every .1 and store
                 just these 11 values.

you can do

.tran 0 1 1 trace=a <= only compute required time steps, store all of
                       them

to get more relevant data.

and... depending on your plotting library, it might be useful to let the
user choose the interpolation method. extra points for visible error
margin.
