time-axis in plotting curves from CDF file

[Boyin Huang <huang_boyin@xxxxxxxxx>]

Dear All:

I used monthly out put (130*12 month), and calculated
EOFs (space pattern and time series) using annual
average.

Because of the regrid to annual average, the time axis
in time series is set as
 TYEAR = 7, 19, 31, 43, 55, 67, ...in unit of months
when saving a CDF file.

When I plot the time series, using
  let x11 = eof_tm[i=1]
  plot/nolab/line=($ln1)/set             x11
  ppl yaxis ($y1),($y2),($dy)
  ppl xaxis ($x1),($x2),($dx)

The label of X-axis is out of control: The ferret some
how use a default value of x1, x2, and dx, and plot
ticks of "0, 400, 800,1200" months.

How can I control the X-axis, and plot the ticks of
"0, 20, 40, 60, ..." years rather than in months?

Or can I use unit of year rather than month when
saving the CDF file?
