I think that the second snippet answers your question: it is a problem
with the gnuplot pdf terminal code. For some reason, fonts are appearing
oversized compared to other terminals. It seems like we will need to ask
the gnuplot developpers about this.

On the other hand, changing dimensions and font_size can do the trick:

e.g. add

  dimensions = [11,8.5]*254,
  font      = "Arial",
  font_size = 16,

to your draw_cmds.
