Dear Mary, thanks you so much spenting more time on my problem, but unfortunately it does not working in the light of your suggested methods.
thanks again

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.

Dear Mary,
Please have a look on my code is given below. If I don't set trXMinF and trXMaxF it is working but the figure is not correct the lines start away from the y-axis. Please your help in this regard will be appreciable.
thanks again,
kim

Dear Kim,
How are you doing the overlay, and when are you setting trXMinF and trXMaxF? It would help if I could see a script.

Dear NCL users
I’m trying to xy-plotA & plotB. Individually and also when I overlay (plotA, plotB) without trXMinF and trXMax resources it is working properly. When I set trXMinF and trXMax during their overlaying it does not work. If I not set these recourses then the lines are not starting at the initial point. Is there any resource or function available in NCL.
Thanks
kim
