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.

I am not sure if this one shall be considered a bug in axis()...

Personally, I would recommend changing x = x-x(1) in your program.

Sincerely,

Dmitri.
