Do you mean the following?

        p1 = [1; 4];            % vector p1
        formatstring = "@b*";
        plot(p1(1,:), p1(2,:), formatstring);

>From the regular plotting questions on this list we can learn that the Octave 
documentation might need some polishing. Just a reference to the gnuplot manual 
is probably
not enough, in particular since some gnuplot options (e.g. line thickness) are 
not supported
by Octave.

And when it comes to more advanced plotting (eg. 3d-plots) many baisc things 
are undocumented
and very difficult to figure out.

Maybe this is something for a seperate howto document or the Octave wiki?
