Hi Hanh,
	That is just a formatting issue for the axis labels.  Ferret
always treats axes as real numbers but you can reformat what you
see on the plot with the "ppl xfor" command (there is a "ppl yfor"
command for reformatting the y-axis value labels too.)

In your case you would

plot/set mydata
ppl xfor,(i2)
ppl plot

Good luck,
Mick
