The grid lines are drawn at the position of the axis tick marks.

As it is, you have only placed x-axis tick marks at places where
there is a data point.  That is, the tics come (only) from the
  using ... xticlabel(4)

If you want to add in other ticks, you need to use the "add" option for
xtics.  For example:

  set xtics add 1, 1, 10

Would add an additional marks, and grid lines, every 1 unit on x
starting a 1 and ending at 10.
