Re: fatal:XyPlotChanges: error setting overlay object view

I'm not sure if this will work, but instead of setting trXMinF and
trXMaxF explicitly,
try to index your time array for whichever values you want to
actually plot.

For example, if you wanted to start at time "19900101" and end at
"20001231", then
you would do something like this:

   yrs = floattoint(utc(:,0))
   ibeg = where(yrs.eq.1990.and.mons.eq.1.and.days.eq.1)
   iend = where(yrs.eq.2000.and.mons.eq.12.and.days.eq.31)

Then:

   plotA = gsn_csm_xy(wks, time(ibeg:iend), zRegion(ibeg:iend), res)
   . . .
   plotB = gsn_csm_xy(wks, time(ibeg_iend), z1Region(ibeg:iend), res)

The other possibility is to use ut_calendar with an option of -2 to
convert your time to YYYYMMDD, and then plot against these new values
instead of your original time values.

For example:

   new_time = ut_calendar(time, -2)
   . . .
   tm_major_values = new_time(day_1)

Change these to the appropriate YYYYMMDD format:

> res@trXMinF = 17552088 ; set minimum X-axis value
> res@trXMaxF = 17555040 ; set maximum X-axis value

and then:

   plotA = gsn_csm_xy(wks, new_time, zRegion, res)
   . . .
   plotB = gsn_csm_xy(wks, new_time, z1Region, res)

Without knowing what your original time values look like, I'm not
sure what's the best method.
