Dmitri,

If you are looking for a quick solution, there is the alternative of 
using the "gplot" command which allows the mixing of an Octave matrix 
with the commands for gnuplot.  For example, I've built scripts that 
will construct an Octave command that might look something like this:

        gset key outside horizontal screen 0.982,0.36 right top;
        t_p = T_params*[ppos:ppos+N_x_p-1]';
        data = [t_p X_p];
        < bunch of commands that recursively build the plot string...>
        eval(plot_str);

After it is done, the string will look something like

 >  gplot data axes x1y2 using 1:2 title "analog input", data using 1:3 
title "binary output";

That might give you ideas to plot the way you want.
