Here are another suggest (take from this list time ago): octave.
Octave is a mathematical app.
It allow you operate with our data output, for example an average power
consumption graphic:
---------- average wave ---------
function retval = media_de_una_onda (v)
retval = 0;
if (nargin !=1)
usage ("media_de_una_onda (vector)");
endif
if (isvector(v))
retval=linspace(0,0,length(v))';
%
% Se crea retval con la longitud de v
% Se hace la transpuesta ya que linspace
% crea columnas y no filas.
%
retval(1,1)=v(1,1);
suma_int=v(1,1);
%
% Para la primera vez no se necesita
% ningún bucle, despues lo que vamos
% haciendo es ir sumando los valores
% anteriores y haciendo la media.
%
i=2;
while (i <= length(v))
suma_int=v(i,1) + suma_int
retval(i,1) = suma_int/i;
i++;
endwhile
else
error ("media_de_una_onda: El argumento debe ser un vector")
endif
endfunction
----------- end of average wave --------
Sorry for spanish comment.
You can operate with data output applying all mathematical expression
you need; for example get a graphic compare "real wave" with "teorical
wave".
But in my "must list" I need a app that can get graphics with sign point
more fast that I obtain with Octave.
I was looking for it with no success, but in the way I found Kjwaves
[0]. Kjwaves is a front-end for spice engine and have a representation
window. In last conversation with Kurt Peters (developer of Kjwaves), he
shows interest for make a better support for Gnucap. Took a look for
it, perhaps Kurt should do some advances.
Regards.
Salud y Revolución.

Ps: Sorry about for my very bad english.
