 * Creates x-y plot. Has one "x" and several "y" input ports. Values of these
 * ports are grouped by time -- when (t,x) and (t',y) arrive where t==t', it
 * outputs (x,y). (The t, t' times do not appear in the output).

 * Note: the output will *not* be ordered by x, so one should be very cautious
 * with further processing. Connecting an ArrayBuilder is fine.
