This is a problem with gnuplot rather than Octave. Apparently they don't correctly process numbers that are near realmax() of 1.79e308. I executed the "set yrange" command in gnuplot 4.6.2 and it emits the same undefined value error that you saw.

You should probably report this on the gnuplot site. Closing report.
