Here is an example, using data that I define in a Ferret
command, but it would be the same when you read it
from a file.
! file/var=tt bx.dat
let tt = {1988,1989,1990,1991,1992,1993,1994,1995}
! Convert to dates, using the DAYS1900 function.
! The second argument is month, and the third day -
! so if your data should really be centered at the middle
! of the year, you can specify that.
let time = days1900(tt,1,1)
def axis/t/from_data/name=tax/units=days/t0=1-jan-1900
time
plot t[gt=tax] ! labels
year and month tics
! or, use a pplus setting to change the axis labels.
plot/set_up t[gt=time]
ppl txlint 0,1
! label years only
ppl plot

Dear All:I plotted a time series by specifying axis
file/var=tt bx.dat
define axis/from_data/t/name=xaxis tt[d=1]which plots the x-axis as "1988.0 1990.0 ... 2000.0" etc.
I wish to have the axis format as "1988 1990 .... 2000" etc or even "88 90 .... 00" etc.
How can I do this in ferret? Thank you very much.
