I'm getting the message in the subject and can't figure out why, since

    axis([t(1), t(100), -3*median(lw(1,:)), 3*median(lw(1,:))]);

axis command does "%g" string formatting when composing range command for gnuplot.
It make only 5 digits precision so you end up with command sent to gnuplot
set xrange [24.99500:24.99500]
which is bad.

Changing "%g" -> "%.16g" in axis.m (around line 260) would provide
gnuplot (at least the version I have) with as much accuracy as it can handle.
I still deffer it to John to make a final judgment in this case...
