 Hi Najib,I have looked at your script and read your original query a few times now and I'm still not clear as to what you are trying to accomplish.  If you could provide a more detailed explanation about what you are trying to accomplish I think that would help the ncl-talk community in assisting you.Adam

 Hi Najib,I see the issue. I did not see from your original ncl-talk posting that your n do loop is closed rather quickly between lines 26 and 28:do n= 0,nfiles-1      nfiles = nend do
A quick test shows that that syntax will result in nfiles = 0 and then the do loop concludes. I think what you want is to change your coding from this:
do n= 0,nfiles-1   nfiles = nend doprint(files(n))z1 = asciiread(files(n),(/nday+1/), "string")printVarSummary(z1)....wks = gsn_open_wks("png","AOT_550")....plot = gsn_csm_xy(wks, x, AOT_550, res)draw(plot)frame(wks)end 
to this:

do n= 0,nfiles-1
  print(files(n))  z1 = asciiread(files(n),(/nday+1/), "string")  printVarSummary(z1)
....
  wks = gsn_open_wks("png","AOT_550_"+ n)
....
  plot = gsn_csm_xy(wks, x, AOT_550, res)   draw(plot)  frame(wks)
end do
If after you implemented the above you are still having problems respond to the ncl-talk list.Adam

 Hi Najib,I think your script is close. You are redefining the workstation each time through your n do loop. Thus, each time through the do loop the output png file gets overwritten. Change this line:wks = gsn_open_wks("png","AOT_550")to this:wks = gsn_open_wks("png","AOT_550_"+ n)

and I think you will get what you want.
I hope that helps. If not, or if you have further questions, please respond to the ncl-talk email list and not to me personally.Adam

Dear ncl-talk,
I am trying as I'm still at the initial stage learning ncl going through user-guides tutorials etc. I want to plot multiple time series with the parametre from different files (AOT_550_2005 to AOT_550_2013). I have writing the codes (see attached file) but when I run it I got only one plot of AOT_550_2005 not with the remaining years.
Kindly assist on how the remaining years will appear on the plot.I also tried looping but the errors are getting much so I live it this way since there is no error.
Thank you
Najib
