Re: gEDA-user: NGSPICE on KJWaves :plotting AC analysis with DC parameter

["KURT PETERS" <peterskurt@xxxxxxx>]

If you're using kjwaves to run your spice model in ngspice, then it IS run 
in batch mode.  You should add all your analysis using the various tabs and 
then run the whole file.  Your results will then be in one file, but that 
still doesn't mean you can add disparate x-axis, you'll just have to play 
with it.
  You really shouldn't need to have both analyses in the same file, you 
should be able to load each raw file and then, using the keep on current 
graph option, attempt to add the new waveforms.

I didn't get it.. .
Currently I have 2 simulations which I run separately and I wish to
merge them into one output plot:
.AC dec 1000 1e3 10e6
.DC vinpos -2 2.5 0.5
I understand that prior for AC analysis a DC analysis is done in order
to locate the operation point,
So the AC analysis should be on top of the DC analysis.

The desired x axis scale is defined in the ac analysis. 1e3 to 10e6 Hz.
The y axis in this case should be several circuit output plots - each
for a different biasing.
How can it be done? perhaps in NGSpice batch mode?
