Try: 

plot(3, 4)

>From the help for plot:

     If more than one argument is given, they are interpreted as

          plot (X, Y, FMT ...)

     where Y and FMT are optional, and any number of argument sets may
     appear.  The X and Y values are interpreted as follows:
...

          If both arguments are scalars, a single point is plotted.

Also if you want multiple points:

        * If both arguments are vectors, the elements of Y are plotted
          versus the elements of X.

The same help file describes how to set the format to plot points
rather than lines.  Let me know if you need help for that..
