I want to put, at same place, current and voltage graph.
Current is much smaller then voltage, then I want to
multiply the value of current by 50, because this way I can

from gnucap command? Something like "print ac v(vl)
50*i(rl)"?
No. not yet.
The print (also plot, probe,store, alarm) statements do not take
expressions. It will some day, but not now.
I have always thought of things like that as belonging in the
viewing and postprocessing software, but most of the viewing
software is fairly simple.
I think if you are using gnuplot, you can do that in the gnuplot
command.
Or with octave:
octave:10> I_rl_50 = I_rl .* 50
Note the dot (.), is for octave not multiply a vector I_rl (1,X) by a
vector (1,1); in this way you multiply 50 for each one of the I_rl
vector componets, that is you want.
Other people use Python with scypy/pylab extension.
I remember time ago I need to graph a simulation with voltage and
current values. I could obtain two differents axis in plot:
grafica2=[tiempo,int_colector];
%
__gnuplot_set__ ytics nomirror
__gnuplot_set__ y2tics
__gnuplot_set__ arrow
__gnuplot_set__ title '"Conmutación Vce - Ic"'
%
__gnuplot_plot__ grafica1 axis x1y1 title "Vce", grafica2 axis x1y2
title "Ic"
%
"grafica1" and "grafica2" are the waves to plot. There was for a Octave
2.9 version, I believe that Octave 3.X not admit these commands now, but
if you see there are gnuplot commands. Try to look for documentation.
There are many ways how you see.
Salud y Revolución.
