[ncl-talk] Need help fixing the date format in a plot

[Soumik Basu]

Hi,

Thank you for the reply. I already tried that example in time_labels but it
did not work. It gave me an execute error.
fatal:["Execute.c":8640]:Execute: Error occurred at or near line 51 in file
sat_hov_jf_x1.ncl
The variable I am plotting is zonal mean.

Variable: air_z
Type: float
Total Size: 53760 bytes
            13440 values
Number of Dimensions: 2
Dimensions and sizes: [time | 70] x [lon | 192]
Coordinates:
            time: [1919712..1921368]
            lon: [ 0..358.125]
Number Of Attributes: 16
  _FillValue : -9.96921e+36
  long_name : mean Daily Air temperature at 2 m
  units : degK
  precision : 2
  least_significant_digit : 1
  GRIB_id : 11
  GRIB_name : TMP
  var_desc : Air temperature
  dataset : NCEP Reanalysis Daily Averages
  level_desc : 2 m
  statistic : Mean
  parent_stat : Individual Obs
  valid_range : ( 150, 400 )
  actual_range : ( 204.925, 314.85 )
  missing_value : -9.96921e+36
  average_op_ncl : dim_avg_n over dimension(s): lat


These were my resources for plotting:

  wks  = gsn_open_wks ("x11", "sat_time_lon" )

  res                      = True               ; plot mods desired
  res at cnFillOn             = True               ; turn on color fill
  res at cnFillPalette        = "temp_diff_18lev"           ; set color map

  res at tiMainString         = ""   ; title

  res at cnLevelSelectionMode = "ManualLevels"     ; manual contour levels
  res at cnMinLevelValF       = -40.        ; min level
  res at cnMaxLevelValF       =  40.               ; max level
  res at cnLevelSpacingF      = 2.                 ; contour level spacing
  res at cnLinesOn            = False


  restick = True
  restick at ttmFormat = "%N/%D %H:%M:%S"
;  restick at ttmAxis = "YL"
;  restick at ttmMajorStride = 20
  time_axis_labels(data&date,res,restick)

  plot = gsn_csm_hov(wks, air_z(:,{160:290}), res)

Thanks,
Soumik
