Dear Kim,
Thanks for providing your script and data.
I think there's an error in your code. You are setting:
res@trXMinF = 17543328 ; set minimum X-axis value
res@trXMaxF = 17546280 ;
But the actual min/max of your X array, "time", is an order magnitude less than these values:
(0) min/max time:
(0) 1782336
(0) 1785288
This will not work, because you are effectively selecting an X axis range that doesn't contain any of your time values.
If you are trying to set the X axis so it starts exactly where you have the beginning and ending major tick marks, then try this:
res@trXMinF = min(tm_major_values)
res@trXMaxF = max(tm_major_values)
which in your case is the same as this:
res@trXMinF = min(time)
res@trXMaxF = max(time)

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.
