Re: gEDA-user: negative voltage on KJwaves

["KURT PETERS" <peterskurt@xxxxxxx>]

Are you choosing "Mag" for magnitude or "real" or "imag" or ???  when you're 
plotting a particular axis?  Mag will, by defiinition, do 
sqrt(real^2+imag^2), which is positive.  I think that was submitted as a bug 
on sourceforge, when, in fact, it's not... just poor choice on the user's 
part.  See the sourceforge page for KJWAVES for more information.
  I hope that helps.

Kurt

Hello,
I have trouble to get a plot of negative voltage in KJwaves using
Ngspice,
i.e. negative values become positive.
My test netlist is:

V1 n0 0 SIN(0 10 1kHz)
C1 n1 n0 3.3nF
R1 0 n1 1k
.END


When running Ngspice and plot n0 I get nice sine wave.
When I`m importing this net to KJwaves and plotting V(n0) I get the negative 
part of the sine as positive.
Any ideas will be welcome.

Yaniv
