Put the current time, or an index value or something at
the start of the line to use as an X co-ord. Otherwise
gnuplot can't know where to plot the point. The default
behaviour (x y1 y2 ... yN) will work for you then.

Because the space between $4 and $5 in {print $4 $5} is
a concatenation operator.
