[ncl-talk] Error while plotting winds from WRF dataset

Thanks a lot Mary for reciprocating. Actually I wanted to do average for
all time, for that purpose I did concatenated. As per you suggestion, I did
call all the files at a time and then did average over all time steps (for
time being here, temperature parameter, once get rectified will try on
winds) using ncl function dim_avg_Wrap. after that when I go for
contouring, It gives me error as below. It gave me error as

*fatal:Argument type mismatch on argument (0) of (wrf_contour) can *

*not coerce.*Then from one of your earlier answer to above issue, I did
change like instead of taking multiple file a, I give as a[0]. Now facing
follow issue


fatal:syntax error: line 25 in file try_wind.ncl before or near ,
  contour = wrf_contour((a[0],
-----------------------------^

fatal:syntax error: line 29 in file try_wind.ncl before or near ,
  plot = wrf_map_overlays((a[0],
-------------------------------^

Below is the script

  wrf_files = systemfunc("ls
/home/swati/work/analysis/2_cities/Patna/14aug2014/wrf_out_data/3rd_domain/wrfout_d03_2014-08-13*")
  a = addfiles(wrf_files,"r")
  t2    = wrf_user_getvar(a,"T2",-1)
  tt  = dim_avg_Wrap(t2(south_north|:,west_east|:, Time|:) )
  wks = gsn_open_wks("png","try")
  res = True
  contour = wrf_contour((a[0],wks,tt,res)
  pltres = True
  mpres = True
  plot = wrf_map_overlays((a[0],wks,(/contour/),pltres,mpres)
